摘要: Abstract Cutouts are always located in aerospace composite structures to meet specified requirements on the service and functions. The presence of cutout, especially large-sized would result a significant stress concentration, consequently complicated failure mechanism. This paper presents an experimental numerical study post-buckling damage process high-performance carbon fiber reinforced polymer (CFRP), T800/X850, multidirectional laminated specimen. simply supported specimen is with central elliptical cutout subjected shearing load. In analysis, model incorporating both advanced strain softening schemes cross-coupling effect between mechanisms constructed for simulation. Regularizations implemented coupling variables address deficiencies existing access real physical behavior composites. invariant theory employed evaluation delamination. To assess objectivity present model, predictions compared data. predicted propagation patterns show good agreement experiment results.
