temprature dependant material properties

Please login with a confirmed email address before reporting spam

i am using copper electrodes and steel sheets in welding model i want to model the material properties such as resistance thermal conductivity as temperature dependent .
kindly tell me how to define these material properties as temperature dependent in the simulation

Hi

many of the material properties are already temperature dependent, take a look. Basically you defne a function (interpolation or tabular) and refer the material properties to this function. check the doc there is more on that in the material section

Good luck
