本文的目的是利用数值计算和实验测试的互补贡献，建立复合材料层合板的损伤本构关系。对交叉层板（[02/90 n]s）进行的实验测试允许观察和量化层压板中存在的损伤类型。考虑到真实的裂纹的离散方面，数值试验允许确定损伤效应（横向裂纹和由横向裂纹引起的分层）对铺层行为的影响。假设损伤效应通过计算已知，为了确定不同的损伤演化规律，实验观察和结果进行了分析。研究结果表明，90°铺层厚度对横向裂纹的发展有影响，可以用基于应力和能量的准则解释试验结果。
AbstractThe aim of this article is to develop a damage constitutive law for composite laminates by using the complementary contribution of numerical and experimental tests. The experimental tests conducted on cross ply laminates ([02/90n]s) permit to observe and to quantify the damage type present in the laminate. The numerical tests allow to determine the damage effects (transverse cracks and delaminations induced by transverse cracks) on the ply behaviour in taking into account the discrete aspect of the real crack. Assuming the damage effects known by computations, the experimental observations and results are analyzed in order to determine the different damage evolution laws. This study underlines the 90° plies thickness influence on transverse cracks development and the experimental results could be explained by using a criterion based on stress and energy.
