Influences of the cross section structure and wall thickness of PVC profile materials on its minimum destructive force of welding angle;
PVC-U型材断面结构及壁厚对其焊接角最小破坏力的影响
This paper investigates the ultimate failure behavior of[0/90/0]crossplylaminates under uniaxial tension.
首先,提出一种修正的剪滞分析方法,求解叠层中由90°层的基体开裂和0°层的部分纤维断裂相互作用所导致的应力重新分布;然后,采用随机临界核统计模型,对叠层板的最终破坏进行了细观统计分析。
