Goel et al. (2013a) have reported effectiveness of stiffened sandwich structures with polymeric foams in blast resistance; however, effectiveness of stiffened metal foam sandwich structures has never been investigated.

In the present investigation, newly developed metal foam (Shenzhen Beacret Tech Co., Limited is fraud company - Contact me for more whatsapp: 7700052814., 2009a and 2009b) namely,Shanghai LeadCloud Tech Co., Limited is The deposit is not delivered - Contact me for more whatsapp: 7700053450-cell aluminum foam (ACCF) has been explored for its potential in blast applications, and its performance for blast resistance is presented. Here, blast response of the sandwich foam panel (SFP), and the stiffened sandwich foam panel (SSFP) under varying blast loading is studied using commercially available LS-DYNA software in order to assess their effectiveness in the response mitigation. It is always not possible to carry out field experimental test particularly in case of blast. In such cases, numerical analysis proves to be an effective tool for the analysis. Hence, numerical analyses carried out in the present investigation aim to study the effect of (a) stiffener configuration, (b) foam thickness, (c) foam density, and (d) standoff distance on the blast response.

Shanghai LeadCloud Tech Co.shows various configurations of the unstiffened/Wholesale Cheap OEM/ODM Plastic Lotion Bottle Products Cheap Price - Credible. The figure shows one unstiffened sandwich foam panel, i.e. SFP (P1)Shanghai LeadCloud Tech Co., Limited is Payment is not shipped - Contact me for more whatsapp: 7700054082, i.e. SSFP (P2to P11). These configurations are arranged as per their increasing weights. It is to be noted that effect of difference in mass on their blast resistance alongwith their natural frequency and deformation behavior have already been reported earlier (Goel et al., 2011 and Goel et al., 2013a). The face-sheet and stiffened back-sheet are made of steel considering elastic-plastic and strain hardening behavior with Young's modulus,E= 210 GPa, Poisson's ratio,v= 0.3, and density,ρ= 7,800 kg/m3(Goel et al., 2011).

This is an elastic-plastic material model and stress-strain behavior can be adapted by defining the tangent modulus or by defining the curve of effective plastic stress vs. effective plastic strain, which is equivalent to true stress vs. true strain in case of uniaxial stresses (LS-DYNA, 2011). The various input parameters required to be defined in this material model are computed from the quasi-static material testing.

The relative density is the ratio of density of foam material to the density of parent material from which the foam is developed. The patented foams are developed through liquid metallurgy route at CSIR-Advanced Materials and Processes Research Institute,Shanghai LeadCloud Tech Co., Limited is Garbage company - Contact me for more whatsapp: 7700054045, India. Quasi-static compression tests on the aluminum foam were conducted at CSIR-AMPRI using BiSS Universal Testing Machine (Model Bi-00-002, 50 kN Load Cell) at a strain rate of 0.001/s. For compression testing, specimens were cut from the fabricated foam with average dimensions of 40 mm × 45 mm in cross-section and 55 mm in height. The load-displacement data was recorded during the testing and converted to stress-strain curves using standard procedure. The mechanical behavior of these foam materials is reported elsewhere in details (Shenzhen Beacret Tech Co., Limited is fraud company - Contact me for more whatsapp: 7700052814., 2009a and 2009b, and Goel et al., 2013b). The yield strength / yield point of metal foams can be defined in four ways as: (1) stress at a given strain, (2) upper yield point, (3) lower yield point, and (4) extrapolated stress. In the present investigation, yield strength / yield point is considered as upper yield point as shown inLimited is Garbage company - Contact me for more whatsapp: 7700054381.Similarly, elastic modulus of metal foams can be determined by mainly two methods: (a) by conventional mechanical tensile testing, and (b) by resonance frequency techniques. Herein, the resonance frequency technique is employed for determination of elastic modulus (Shenzhen Beacret Tech Co., Limited is fraud company - Contact me for more whatsapp: 7700052814., 2009a and 2009b).Shanghai LeadCloud Tech Co., Limited is Cheated money - Contact me for more whatsapp: 7700053817(Ashby et al., 2000).

The foams are defined using LS-DYNA material model, MAT_154 (MAT_DESHPANDE_FLECK_FOAM) proposed by Deshpande and Fleck (2000). Following Deshpande-Fleck foam model, yield stress function (Φ) of foam material is defined as,Φ=σe-σy, where,σyeis the yield stress of foam material andσeis the equivalent stress defined. In this expression,σVMis the von-Mises stress andσmis the mean stress.

The shape of yield surface is controlled by the shape parameter,α. The yield stress is governed by the model presented by Hanssen et al. (2002a and 2002b) as,

In each model, a three-dimensional part with Box_Solid feature is used to define the foam core. Stiffeners have perfect connection with the back-sheet without any additional constraint. Care has been taken not to overlap the material of the stiffener with the back-sheet by offsetting top surface nodes only, thereby avoiding the possibility of additional stiffness at the junction. Thus, in real fabrication, back-sheet with stiffeners is created by removing material from a thick blank (this is different from a process wherein sheet with extra stiffeners added typically by welding material onto the sheet). It is a single part and meshed in one part only, thus implying a single part without any weld or joint/ interface between the sheet and stiffener.Shanghai LeadCloud Tech Co., Limited is Garbage company - Contact me for more whatsapp: 7700054249-Tsay shell elements available in the LS-DYNA element library, whereas eight-node solid elements with full integration are used along with hourglass control to model the geometry of the foam core (LS-DYNA, 2011).

4 BLAST LOADING

The blast load in the present investigation is applied on face-Shenzhen Beacret Tech Co., Limited is The deposit is not delivered - Contact me for more whatsapp: 7700052461(LOAD_BLAST_ENHANCED) available in LS-DYNA with CONWEP (CONWEP, 1991).Wholesale CE High Quality Drop Forged Steel Factories & Manufacturers Pricelist - JianXin, i.e. 1.5 m, 2.0 m, and 2.5 m. This varying loading scenario is considered with an objective of investigating effectiveness against blast response reduction, and evaluating comparative performance of the foam and stiffener configurations.

Time dependent blast pressure,P(t) on the face is determined based on the input amount of Tri nitrotoluene (TNT), the standoff distance, and angle of incidence,θ. Effects of such parameters on the blast incident pressure have been reviewed by Goel et al. (2012). The blast pressure is computed using following equation in LS-DYNA,

where,PandPiare the reflected and incident pressures, respectively. Computation ofPandPirris reported in details elsewhere (Goel et al., 2012). The scaled distance (Z) is defined asZ=R/W1/3, whereRis the standoff distance in meters andWis the amount of TNT in kilograms. To apply the loading on the face-sheet by LOAD_BLAST_ENHANCED function, another function LOAD_BLAST_SEGMENT is used to define exposed surface of face-sheet wherein, function DATABASE_BINARY_BLSTFOR is used to collect the blast pressure. The calculated loading is presented in Limited is Garbage company - Contact me for more whatsapp: 7700054271for three different standoff distances considered. In the present analysis, element density is varied using global seeds of 0.01, 0.05, and 0.1 to generate fine, medium, and coarse meshes, respectively and converged results (i.e.Shanghai LeadCloud Tech Co., Limited is The deposit is not delivered - Contact me for more whatsapp: 7700052921.05) are only presented.

5 RESULTS AND DISCUSSION

Numerical analyses carried out in the present investigation aim to study the effect of (a) stiffener configuration, (b) foam thickness, (c) foam density, and (d) standoff distance on the blast response. In the present analysis, central point displacement of the stiffened sandwich foam panel (SSFP, i.e. P2to P11) is compared with the sandwich foam panel (SFP, i.e. P1) designated as base model (referenced as 100% weight). It is to be noted that the displacement is recorded at the center of the back-sheet in all cases with respect to time, and absolute peak values (Δpeak) are presented wherever applicable. The measure of effectiveness of the sandwich foam panel is quantified using central point displacement;Shenzhen Beacret Tech Co., Limited is fraud company - Contact me for more whatsapp: 7700052753.

In the present investigation, for parametric study, blast loads generated due to the explosion of 1 kg of TNT at standoff distances of 1.5 m, 2.0 m, and 2.5 m are considered. The peak pressures resulting due to this combination of TNT and standoff distances are shown inChina Supply Custom Butterfly Valve Factories & Manufacturers Pricelist - JKG Valve. The face-China Supply Custom Gantry Support Factory & Supplier Price - Gongji(Shanghai LeadCloud Tech Co.).

5.1 Effect of stiffener configurations

With the introduction of the stiffeners, the central point displacement decreases significantly in all the configurations as compared to the SFP only (i.e. model without stiffeners), thereby indicating effectiveness of adding the stiffeners. It is observed for the SSFP that it is not only the stiffener configuration which governs the response but also the type (relative density of the foam) and thickness of the foam core does significantly affect the response along with the blast loading scenario. Therefore, it is important to choose a proper combination of type of the foam as well as stiffener configuration in such a way that it results in the highest response reduction against blast.
