View Full Version : Abaqus bilinear material

Would anyone have any information on how to implement a bilinear material
definition in Abaqus?

The only way I am aware of is through the use of a user-defined material
(UMAT). But, I am unsure of how to code the material definition. Could
someone who has coded something similar please offer some assistance? Or,
if there is alternative method.

The data I am working with is the value of the Young's modulus of
elasticity corresponding to a region of strain and an additional value of
the Young's modulus for the second region of strain through failure/maximum
strain.

Thanks in advance for any feedback
