泡沫夹层结构复合材料准静态压痕实验
Foam-Core Sandwich Structure Composites Subjected to Quasi-Static Indentation
摘要
Abstract
The damage processes and forms of two different heights of foam-core sandwich structure composites subjected to quasi-static indentation were studied. The curves of contact force and displacement as well as the damage morphologies of different displacements were obtained by controlling the displacements. The differences of damage processes between thick foam-core materials and thin foam-core materials were also compared. The result shows that the damage process consists of foam-core collapsing, foam-core cracking, skin delaminating and skin-core debonding;the damage form is that the cracks are ±45° in the direction of foam-core thickness when the core is thick,and 90°when the core is thin.关键词
