Abstract : Report Objective: Computationally determine and assess the effects of interply layer progressive degradation on the structural response of a layered composite beam. The structural response of interest includes: Bending/Flexural (3-Point); Buckling; Free Vibrations; Periodic Excitations (Forced Vibrations); Impact.
