Abstract
The computer program PANDA2 for minimum weight design of composite, stiffened cylindrical or flat panels made of composite material is described. The capability of PANDA2 has been expanded to handle truss-core sandwich panels. The new capability is demonstrated in this paper with an example: minimum weight design of a truss-core sandwich panel under axial compression, in-plane shear, and normal pressure. At the design load the panel is in a locally postbuckled state.
