| 摘 要： | 应用泡沫金属弹撞击加载的方式研究了固支泡沫铝夹芯拱的塑性动力行为.对夹芯拱的变形与失效模式进行了系统的分类和分析,并考察了发射弹的动量、面板厚度、泡沫芯层厚度及曲率半径对其抗撞击性能的影响.夹芯拱的变形与失效模式可分为3种形式:前面板在作用区域的压入失效和整体的大变形、芯层的压缩失效和剪切失效以及后面板的非线性大变形....

| Abstract: | The dynamic response of clamped sandwich arch with aluminum foam core under the impact loading of aluminum foam projectile was investigated.The deformation/failure modes of sandwich arch were classified and analyzed systematically.The effects of projectile momentum,face-sheet thickness,thickness of foam core,and radius of curvature on the structural response were analyzed.The deformation/failure modes of sandwich arch can be classified as the indenting failure in the loading area and the large global deform... |
