An anisotropic damage model of elasticity based on a series coupling method

Linlin Sun, Weiping Hu, Qingchun Meng


This paper presents the study on an equivalent anisotropic elastic damage model, i.e. the series model, which is constructed by coupling the truss microstructure in series with an isotropic volumetric elastic element. This model can simulate the material with any thermodynamically admissible values of Poisson’s ratio as well as inherit the simplicity of the truss microstructure model. Further discussion indicates that at least two independent scalars are needed to characterize the isotropic damage. This coupling method presented in this work provides a new way to research anisotropic damage of materials.
