Code underlying the MSc. thesis: Limiting microcracks and hydrogen permeability in thermoplastic composites for LH2 storage

As part of an MSc thesis there is researched how microcracking and hydrogen permeability for thermoplastic composites under tensile loading at deep cryogenic conditions can be limited to a predefined level in order to fulfill the requirements for long-life, vacuum-insulated composite liquid hydrogen tanks for civil aviation. As part of this research, there is made use of this XFEM-SCZM model that simulates the materials' mechanical behaviour by creating matrix cracks and delamination. It does so by using Python scripting for Abaqus.

本研究作为硕士学位论文的一部分，针对深低温拉伸载荷条件下的热塑性复合材料，探究了如何将其微裂纹与氢气渗透率控制在预设水平，以满足民用航空长寿命真空绝热复合液氢储罐的性能要求。
本研究采用扩展有限元-内聚力区模型（XFEM-SCZM），通过生成基体裂纹与分层脱粘来模拟材料的力学行为，该模型依托适配Abaqus的Python脚本实现。
