摘要
基于理想弹塑性材料假设和Von-Mises屈服准则,考虑厚壁圆筒三向应力分布的不均匀性以及圆筒的几何特性,推导给出了厚壁圆筒在内压和轴向力共同作用下的极限载荷表达式。文中的理论解与前人的解比较结果表明,文中的解比现有解精确,用于薄壁圆筒时,其解与现有的薄壁解一致。
A limit load solution for a thick -walled cylinder under combined internal pressure and axial tension is derived based on Mises yielding criterion, considering the effect of three dimensional stress distributions. The new solution is compared with the results from others for selected cases and the results show that the solution obtained in this paper is more accurate. The predictions thin -walled cylinders using the new solution are compared with results of other thin - walled cylinder solution with very good agreement.
