Experimental tests and numerical studies were performed to investigate the burst performance of thermoplastic composite pipes (TCPs) under internal pressure. A progressive damage model is established to predict the burst behavior of TCPs, in which different failure criteria and the damage evolution of a composite material are considered and directly incorporated into the ABAQUS with a user-defined UMAT subroutine. A series of burst tests on TCPs with different numbers of reinforced layers were carried out, and experimental results were in good agreement with the corresponding numerical predictions. In addition, based on the adaptive progressive damage model, a parametric study into winding angles of TCPs with eight reinforced layers is conducted to evaluate their burst performance.

进行了实验测试和数值研究，以研究热塑性复合管（TCP）在内部压力下的爆破性能。建立了渐进式损伤模型以预测TCP的爆发行为，其中考虑了不同的失效标准和复合材料的损伤演变，并通过用户定义的UMAT子例程将其直接合并到ABAQUS中。对具有不同数量加强层的TCP进行了一系列的爆破测试，实验结果与相应的数值预测吻合良好。此外，基于自适应渐进式损伤模型，对具有八个增强层的TCP的缠绕角度进行了参数研究，以评估其爆破性能。
