Dear members,

I am a master student. For my master thesis I need to develop a UMAT code for epoxy resin to simulate the residual stress during curing. The problem is that i am an abaqus beginner. If some of you have a viscoelastic UMAT code with Kelvin elements or Maxwell, can he sends it to me please.
PS: I have tested the Abaqus documentation UMAT example but there are 3 parameters which are not defined.

Thank you in advance
