  • 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
