中文摘要：
从层合板准静压损伤机制出发，根据渐进累积损伤原理，建立了复合材料层合板准静压损伤的有限元模型，合理地描述了复合材料层合板内部不同形式的损伤及其累积过程，进而讨论了在相同的层合板厚度下，单向铺层厚度对层合板准静压损伤的影响。结果表明，单层厚度的增加会加大层合板的基体开裂损伤以及分层损伤的程度，但有利于抑制纤维断裂的发生。
英文摘要：
Starting from the indentation damage mechanics, a numerical model of laminated composites subjected to quasi static indentation was established on the basis of progressive damage mechanics. The different kinds of composite damages and their progressive processes were quantitatively analyzed. Furthermore, under the condition of same laminates thickness, the effect of single ply thickness on the indentation damage was discussed. The results show that the increase of single ply thickness can enlarge the matrix damage and the delamination degree, whereas it can restrain the development of fiber fracture.
