Keywords: composite, damage, impact, residual strength
The finite element tool CODAC (Composite Damage Tolerance Analysis Code) developed at DLR is presented. CODAC can quickly evaluate low-velocity impact behaviour and residual strength of composite structures. While originally being developed for the analysis of monolithic structures (stringer-stiffened panels), it is presently being extended for application to sandwich structures.
