近年来复合材料在船舶与海洋工程领域得到快速发展。船舶在服役周期内受载复杂，主要承载板材除受典型的面内拉压外载外，免不了遭受横向波浪载荷作用。研究复合材料层合板在不同载荷形式下结构的响应特征与损伤演化特性，有助于先进复合材料的性能评估及优化设计。本文采用三维实体单元及内聚力单元建立复合材料层合板模型进行计算分析，考察拉压载荷下层合板的极限承载能力与渐进失效过程，研究在横向载荷下层合板结构强度，对比分析其层内及层间损伤模式的差异性。
Composite materials have been developed rapidly in the naval architecture and ocean engineering over recent years. During the service period, ships experience complicated loads. The primary plates suffer not only in-plane tension and compression but also transverse wave loads. Researches on the structural response and damage evolution characteristics of composite laminate plates under different load forms are helpful for the performance evaluation and optimization design of advanced composite materials. This paper adopts three-dimensional solid elements and cohesive elements to establish a composite laminate plate model. Firstly, the ultimate bearing capacity progressive failure process of the laminate plate with tension and compression loads are analyzed. Then, the structure strength of the laminated plate with transverse loads is investigated, and the differences of the inter- and interior- layer damage modes under different load forms are discussed in detail.
