Sandwich panels are widely used for energy absorbing applications in cases of low and high velocity impacts. The core itself is capable of absorbing energy by progressive collapse, while the skins are necessary for uniformly distributing the local ve

A damage tolerance analysis methodology for Laser Beam Welded (LBW) structures is proposed. The Residual Stresses (RSs) of LBW T-joints are initially calculated through the thermo-mechanical simulation of the LBW process. Through cracks of variable l
