Based on elastic mechanics, a model was established to simulate the thermal residual stresses and strains in composite material barrel with metal liner. The changes of the winding angles of composite materials and the temperature during curing process were considered. 根据圆筒的弹性力学理论,建立了带金属内衬的纤维增强复合材料身管的热残余应力模型,考虑了复合材料加工固化过程中的温度和缠绕角度等参数的变化。
