摘要
用统一平面应变滑移线场理论,得到了拉压性能不同材料的厚壁圆筒的极限荷载统一解,它也可以适用于拉压强度相等的材料,能充分发挥材料性能,减轻结构重量,取得多方面的经济效益。
The unified solution of the ultimate strength has been obtained of the thick-wall cylinder, which is made from a material with different tensile and compressive properties. The method is also applied on the material that tensile strength is equal to compressive strength. The benefit using this method is to make full use of the strength of materials and also to decrease the weight of the structure. We, therefore, could get the best engineering records and the economic benefits.
