【摘要】 对两炮喇叭口爆炸成形强化护环拐点离上端近的情况进行分析,采用轴对称圆柱薄壳有矩理论,构造新的位移函数,得出该情况下残余应力的解析解.这就为求解拐点上移后残余应力的解析解打下了基础,其在理论和工程实际中都有很大的价值.更多还原

【Abstract】 We analyse the instance that the inflexion of the retaining ring is near to the top,adopt the theory of the axisymmetry column this shell,and construct a new displacement function,then work out the analytical solution of the residual stress under this instance.This conclusion establishes the foundation for the residual stress when the inflexion moves up and it is very valuable in theory and engineering.更多还原
