On effective mechanical properties of an orthogonal corrugated sandwich structure

On effective mechanical properties of an orthogonal corrugated sandwich structure

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 an...
