Abstract: A simple formula is suggested for the upper bound on the asymptotic pressure in a spherical cavity surrounded by an infinite elasto-plastic medium. The uniaxial stress-strain curve is assumed ...

Abstract: The nonlinear problem of a spherical cavity surrounded by an infinite elasto-plastic medium, and subjected to uniform radial loads, is considered. The material is assumed to be incrementally ...

Abstract: Buckling behavior of sandwich beams with a soft core is presented. The buckling analysis consists of formulation of linear and nonlinear behavior equations, boundary conditions, and continuity conditions. The beam construction ...

Abstract: Localized load effects using a high-order theory for the bending behavior of a sandwich panel with a “soft” core (i.e., flexible) in the vertical direction that is based on variational principles are presented. The theory ...

Abstract: The stability of simply supported conical shells under axial compression is investigated for 4 different sets of in-plane boundary conditions with a linear Donnell-type theory. The first two ...

Abstract: The bending behavior of an unsymmetrical sandwich beam with a flexible, foam‐type core is investigated analytically. The beam consists of different skins, upper and lower, metallic or composite‐laminated, and a soft core. ...

Abstract: A general, high‐order theory based on variational principles is presented for the bending behavior of a sandwich beam with a core that is vertically flexible. The theory embodies a rigorous and systematic approach to the ...
