工程中的理想结构单元法

Idealized Structural Unit Method in Engineering

理想结构单元法在于将结构分成最大可能的单元。以简单的形式归并几何非线性与材料非线性。按增量形式加载,直至达到极限强度。算例结果与非线性有限元分析结果十分吻合。

Idealized structural unit method is based on subdivision of the structure into the largest possible structural units.Geometrical and material nonlinearities are incorporated in a concise form.The load is applied in increments until ultimate strength is reached. The numerical results are very much in agreement with ones by using nonlinear finite element method.
