hello every body
I am asking you about changing property during steps of model
I need to change some material properties from one to another between first step to second step
how can I do this
plz help me

with certain material models you can define stress-strain response as a function of temperature.

then you can vary temperature in different steps to vary mechanical response.

If the temperature is needed as a solution variable, then the same can be done with a Field Variable.
