A damage model for tensile test in Abaqus



Abaqus damage model explanation

This product explains the Abaqus damage model. It is beneficial to simulate part failure during the process using element deletion. Before explaining the model in Abaqus it is necessary to understand the background of damaged model and material behaviour.


Abaqus/Standard and Abaqus/Explicit offer a general capability for predicting the onset of failure, and Abaqus/Explicit offers a capability for modeling progressive damage and failure of ductile metals. Damages in a structure are caused by material degradation due to initiation, growth and coalescence of mircocracks/voids in a ‘real-life’ material element from monotonic, cyclic/fatigue, thermo-mechanical loading or dynamic/explosive impact loading [1].

Damage mechanics 

The theory of damage mechanics takes into account the process of material degradation due to initiation, growth and coalescence of micro-cracks/voids in a ‘real-life’ material element under monotonic or cyclic or impact or thermo-mechanical loading. A valid material failure criterion must therefore take into account the process of progressive material degradation/damage under either static or dynamic/fatigue loading [1].


Abaqus offers a general framework for material failure modeling that allows the combination of multiple failure mechanisms to act simultaneously on the same material. Material failure refers to the complete loss of loadcarrying capacity that results from progressive degradation of the material stiffness. The stiffness degradation process is modeled using damage mechanics [1]

Tutorial video

In this video, you will learn how to create a simple tensile test model using damage criteria in Abaqus. Damage criteria helps users simulate the element deletion to study part failure. There are two factors that are necessary to define damage model: part failure and element deletion. The first criteria is necessary to reduce the stiffness matrix in the element. The second one is necessary to remove the elements. An explicit model without the mass scaling factor was used in this model. The video is short and you can learn this in less than 11 minutes. You will have the output and Abaqus CAE file.

 In this video, we avoid giving too many details so you can easily learn. Here you can find the following files:
