摘　　要：根据在等效外力下桁架单元与正六面体单元的剪切、受拉、受压的应力应变曲线相同,建立了一个新单元模型,并求解了弹塑性力学的计算问题,其结果与其他方法计算结果吻合良好。The stress-strain curves of shear, tension and compression under the equivalent external forces of the truss element and the regular hexahedronelement are the same, a new element model is presented. The elastic-plastic problems can be solved by using the new element model,and the calculation results are in good agreement with other methods.
