TL;DR: In this article, the dynamic deformation of both edge clamped stainless steel sandwich panels with a pyramidal truss core and equal mass monolithic plates loaded by spherically expanding shells of dry and water saturated sand has been investigated, both experimentally and via a particle based simulation methodology.

TL;DR: In this article, a higly-nonlinear structural optimization problem for the sandwich panel with external thermal protection layer that can be used in the spacecraft systems is formulated based on simplified analytical solutions of structural mechanics and heat transfer problems, which are suitable for the preliminary design considerations.
Abstract: In this work we solve a higly-nonlinear structural optimization problem for the sandwich panel with external thermal protection layer that can be used in the spacecraft systems. Objective function of the problem is the mass per unit area of the panel. Constraints are formulated based on the simplified analytical solutions of structural mechanics and heat transfer problems, which are suitable for the preliminary design considerations. The set of design variables includes the geometric parameters of the panel and additional microstructural parameter—porosity of the heat protection material. Direct random search and simulated annealing method are applied to solve considered problem. Change of limit states and optimal configurations of the panel are studied for different levels of the mechanical loading.

TL;DR: In this paper, the elastic and plastic buckling behavior of pyramidal truss core sandwich panels with local damages under in-plane compression is studied experimentally and numerically, and a finite element model in conjunction with random number is developed to simulate the buckling behaviour of the panel with randomly distributed damages in a specific region.

TL;DR: In this paper, the minimum weight criterion of a sandwich panel with respect to a given bending stiffness and strength is verified for a number of sandwich constructions consisting of a foamed PVC core and glass fibre reinforced epoxy faces.

TL;DR: In this article, two types of new hybrid cores were proposed, one consisting of polymer resin reinforced by vertically (transversely) aligned continuous metallic millitubes, denoted as Type-I sandwich panel, and the other was made of polymer resins reinforced by horizontally (longitudinally)aligned continuous metallic micro-machines and polymer matrix.
