Eccentrically loaded sandwich panels

International Journal for Numerical Methods in Engineering, 1977
AbstractThe paper deals with the design of eccentrically loaded sandwich panels in civil engineering structures. A theoretical analysis taking into account the non‐linear stress–strain properties of the materials and the influence of shear deformations is proposed. A computer program based on the described algorithm is used to solve a numerical example.
