ductile damage

Hi All,

I want to model a dogbone specimen made from polycarbonate.

I model it using linear elastic plasticity coupled with ductile damage model.

For the damage, we are going to use the tabular form to described the damage evolution d with respect to equivalent plastic strain epsilon_p.

In abaqus, it is written that we need to input the d with respect of equivalent plastic displacement (u_p) instead of epsilon_p via equation u_p = epsilon_p \times L; where L is the characteristic length.

Hello

I am trying to model tensile test simulation of a AL7075 and i have real strain-stress curve of material.  To complete ductile damage simulation modelling  in ABAQUS ductile damage material specifications are required. If anyone can share  an tensile test simulation inp. file ı would be pleased.

Hi all

I am M.Sc. sutdent in Istanbul Technical University and my research subject is comparision of several ductile damage models both computationaly and experimentally.

I am trying to compare ductile damage models such as Freudenthal,Cockroft,Ayada ,Brozzo etc. computationally using ABAQUS and seeking a way to implement these damage models in ABAQUS.

To obtain each models damage result individually should damage model be implemented in ABAQUS or can a regular tensile test results be used for calculation of damage values.
