摘要
基于正六面体微元与桁架单元的受力变形等效,建立了一个桁架单元新模型,求解了钢材的弹塑性平面应力问题和空间问题,并通过大量的计算实例,验证了该新单元模型具有良好的计算精度。
Based on stress deformation equivalent of vertical hexahedron microelement and truss element, a new truss element model is presented. It can be used to solve the elasto-plastic plane stress problem and spatial problem of steel. Through a large number of examples, the new element model can be found to have good accuracy.
