摘要
本文利用静力关系对弯曲梁损伤承载力进行研究,给出了三种模型状态下弹塑性、脆塑性、线性软化受损面的计算公式,同时结合有限元技术建立将应变模态和曲率模态相联系,给出损伤承载力识别的求解过程,为工程结构损伤分析提供可行方法.
In this paper,the bearing capacity of bending beam damage was studied by using the static relationship.Three model calculation methods of elastic- plastic,brittle plastic and softening damage surface were came up. At the same time,the strain mode was connected with the curvature mode with the help of finite element technique. The bearing force solving process of damage identification was discussed and which provides a feasible method for structural damage analysis.
