Compressive strength after blast of sandwich composite materials
Composite sandwich materials have yet to be widely adopted in the construction of naval vessels despite their excellent strength-to-weight ratio and low radar return. One barrier to their wider use is our limited understanding of their performance when subjected to air blast. This paper focuses on this problem and specifically the strength remaining after damage caused during an explosion. Carb...
متن کاملNon-linear Dynamic Analysis of Steel Hollow I-core Sandwich Panel under Air Blast Loading
In this paper, the non-linear dynamic response of novel steel sandwich panel with hollow I-core subjected to blast loading was studied. Special emphasis is placed on the evaluation of midpoint displacements and energy dissipation of the models. Several parameters such as boundary conditions, strain rate, mesh dependency and asymmetrical loading are considered in this study. The material and geo...
متن کاملNon-linear Response and Dynamic Buckling Analysis of a Cylindrical Sandwich Panel with a Flexible Core under Blast Loading
In this paper, three-dimensional displacement response of a cylindrical sandwich panel with compressible core under the action of dynamic pulse loading is addressed using the extended high order sandwich panel theory. Also, local dynamic pulse buckling of facesheets is studied by considering the Budiansky-Roth buckling criterion. It is assumed that the sandwich panels consist of orthotropic fac...
متن کاملNon-uniform Hardening Constitutive Model for Compressible Orthotropic Materials with Application to Sandwich Plate Cores
A constitutive model for the elastic-plastic behavior of plastically compressible orthotropic materials is proposed based on an ellipsoidal yield surface with evolving ellipticity to accommodate non-uniform hardening or softening associated with stressing in different directions. The model incorporates rate-dependence arising from material rate-dependence and micro-inertial effects. The basic i...
متن کاملAnalysis of sandwich TPS panel with functionally graded foam core by Galerkin method
The method of Fourier analysis is combined with the Galerkin method for solving the two-dimensional elasticity equations for a sandwich thermal protection system (TPS) insulation panel with foam core subjected to transverse loads. The variation of the Young s modulus through the thickness is given by a polynomial in the thickness coordinate and the Poisson s ratio is assumed to be constant. The...
