摘　　要：以指数函数近似表示非线弹性材料的应力－应交关系，推导出了非线弹性材料平面杆系结构应力应变计算的普遍表达式，编制了通用程序，使这一类问题有了一个通用的解题方法．it is a complex structure of bars thatall bars are arbitrarily pinned to a rigid body andother structures of bars can be considered as its special cases. In the structure, tensile bars are usually made from a nonlinearly elastic high-strengthmaterial. The exponential function is used to approximately represent the stress-strain curve of thenonlinearly elastic material. The universal expression of the stress-strain calculation in the nonlinearly elastic structures of bars has beed derived andthe general program has been worked out.
