This article deals with the development of a new intralaminar interface in order to extend the semi-continuous strategy already developed by the authors for impacts on thin composite laminates to thicker ones. Based on medium experimental observations scale, the new interface introduced aims at capturing transverse resin cracks occurring between fibre bundles of a unidirectional ply. The new element is implemented in the commercial finite element software Radioss®. Results of impact simulations performed on thick HTA7-913 plates (various thicknesses) are compared with experimental ones, and show good agreements in terms of both damage sizes and load-displacement curves.

开发一种混合单元来模拟冲击载荷下厚复合板的层内损伤

本文讨论了一种新的层内界面的开发,以将作者已经开发的半连续策略扩展到更厚的复合层压板。基于中等实验观察尺度,引入的新界面旨在捕获单向层的纤维束之间发生的横向树脂裂纹。新元素在商业有限元软件 Radioss® 中实现。在厚 HTA7-913 板(各种厚度)上进行的冲击模拟结果与实验结果进行了比较,并且在损伤尺寸和载荷-位移曲线方面表现出良好的一致性。
