两炮成形强化护环拐点外移时残余应力的解析解

Analytical solution of residual stress at inflexion of retaining ring moves outside

对两炮成形强化护环拐点外移时的情况进行分析,采用轴对称圆柱薄壳有矩理论,构造位移函数,得出该情况下残余应力的解析解.

This paper analyses the instance that the retaining ring moves outside, adopt the theory of the axisymmetry column thin shell, and constructing a displacement function, works out the analytical solution of the residual stress under this instance. The conclusion is very valuable in theory engineering.
