摘要
根据二维极坐标系的弹性力学控制方程 ,引入状态变量 ,建立多层压力管的状态方程 ,并由状态方程同时解出厚薄壁内外应力与位移的多种变量问题。文末给出的数值算例 ,其计算结果精度高。
Based on control equation of elasticity in polar coordinates,the state vector and the state equation of the compressed pipe are derived.Meanwhile,the stresses and displacements of the thick-thin compressed pipe with multi-kind variable problems are solved from the state equation.The numerical example is given with the accurate computational results at the end of the paper.
