Hi. I am modelling solid timber under 4 point bending using Hashin damage model from experiments. However, I dont understand how damage evolution law under material property degradation works and how to assume or derive the reduction coefficients? If any of you has information on this (based on manual, academic paper or anything), please let me know.

Thanks.

Hi,

Please see if the following paper (sharing the paer title) helps:

Nonlinear finite element analysis of timber beams and joints using the layered approach and hypoelastic constitutive law
