In this paper, solid rocket moter oblique nozzle contraction shells stress profile is analysed and calculated by means of finite element method. 对固体火箭发动机斜喷管收敛段壳体应力场采用有限元法进行了分析和计算。
The cells were contraction; The Contribution of Restrained Solid State Contraction of the Weld on the Welding Residual Stress Forming Procedure 细胞突起呈念珠状变化。焊缝固态收缩对残余应力形成过程的作用
In the cooling phase, the nugget instantly change to solid state, the isotherm remains the ellipse contraction, and the temperature gradient gradually flatten. 在冷却阶段熔核瞬时完成凝固结晶,焊接区内等温线保持椭圆形收缩,温度梯度逐渐趋于平缓。
