Abstract

Effective mechanical properties of an orthogonal corrugated sandwich structure have been investigated analytically and numerically. A necessary condition for geometrical design of orthogonal corrugated sandwich structure is obtained. The elastic properties and the collapse surfaces are identified and explored. Finite element simulations are carried out to validate the analytical model. It is shown that the analytical predations are in good agreement with numerical results. Moreover, the orthogonal corrugated sandwich structure has better shear performance than the conventional corrugated sandwich structure by appropriate design.
