本文总结了一项研究，其重点是了解中心位置的圆孔加载到后屈曲挠度范围内的板的破坏机制。这项研究是数值和实验性质的，目标是利用现有的失效数据和应力分析对失效进行先验预测。采用最大应力失效准则预测失效，同时考虑了层内应力和层间应力。对四种层合板进行了研究。讨论了模式相互作用现象，即从一个变形位形跳跃的现象
This paper summarizes a study focused on understanding the failure mechanisms present in a plate with a centrally located circular hole loaded in-plane into the postbuckling range of deflections. The study was numerical and experimental in nature and had as a goal the a priori prediction of failure using existing failure data and a stress analysis. The maximum stress failure criterion was used to predict failure and both intralaminar and interlaminar stresses were considered. Four laminates were studied. The phenomenon of modal interaction, or the jumping from one deformed configuration, is discussed
