| 摘 要： | 采用钻孔法测定了长纤维局部增强的铝合金试样中增强区与非增强区之间的宏观残余应力,利用有限元法对此进行了模拟计算.结果表明:增强区与非增强区之间存在着明显的宏观残余应力,但分布很不均匀.在增强区和非增强区大部分区域,残余应力并不大,而宏观边界附近的非增强区以及增强区的局部存在高残余拉应力微区.在50%纤维局部增强的试样中...

| Abstract: | The macroscopic residual stresses between reinforced and unreinforced zones in long fibre reinforced aluminum samples were measured with the borehole method and simulated with FEM.The results indicate that there exist obvious macroscopic residual stresses in the samples,which are distributed very unequal.It was found that the macroscopic residual stresses at most locations in both the reinforced and unreinforced zones were not harmfully high.However,there were some small region with large tensile residual s... |
