时间序列模型建立 损伤识别(Damage identification by time series model)

BeamElementmm 为生成二维平面梁单元的一致质量矩阵 BeamElementStiffness 为生成二位梁单元刚度矩阵 BeamElementStiffness 为组装刚度矩阵和质量矩阵的程序 本程序可以进行有限元模型修正和结构损伤识别，优点是基本解决了测量信息有限的问题。(BeamElementmm is a consistent mass matrix for generating two-dimensional planar beam elements BeamEleme

用刚度文件FEM，对模型进行不同单元的损伤识别，同时得到损伤程度(The stiffness file FEM is used to identify the damage of different elements of the model, and the damage degree is obtained at the same time.)
