摘要
由于很多均匀压力作用下的厚壁球壳都是拉压弹性模量不同材料制成的,所以采用弹性理论研究了均匀压力作用下的拉压弹性模量不同厚壁球壳的变形问题,推导出了拉压弹性模量不同厚壁球壳的应力公式.利用拉压弹性模量不同厚壁球壳的应力公式并结合莫尔强度理论确定了拉压弹性模量不同厚壁球壳的壁厚.算例分析表明,对于均匀压力作用下的拉压弹性模量不同厚壁球壳的计算,采用拉压弹性模量不同弹性理论更为合理.
It was studied that the deformation of thick wall spherical shell of bimodulous materials under uniform pressure with elastic theory, a lots of thick wall spherical shells under uniform pressure were made of bimodulous materials. And stress formula for thick wall spherical shell was derived, with which the mohr theory the thickness of wall was calculated. The numerical example shows that the bimodulous elastic theory reasonable for the calculation of thick wall spherical shell of bimodulous materials under uniform pressure. strength IS more
