Hi all, I am implementing the constitutive behaviour of two-crystal CuAlNi shape memory alloy during uniaxial loading using UMAT. My aim is to pass single crystal to polycrystal model. So, I am trying two-crystal problem firstly. I have no trouble with implementing two-crystal (one crystal has...

Hi all, I am implementing the constitutive behaviour of CuAlNi shape memory alloy during uniaxial loading using UMAT. My question is that: Stress decreases during phase transformation in our model but I can't do this in UMAT. When stress is needed to decrease, abaqus job stops and there is no...

Hello all! I am having some trouble formulating Jacobian for one of the martensitic phase transformation model in shape memory alloys. There is no problem when there is only austenite phase. It is elastic and elastic stiffness tensor is equal to Jacobian tensor. However, during phase...

I installed Abaqus 6.10-1 and Intel Visual Fortran 11.1.065. After I added to target of Abaqus Verification and Command this: "C:\Program Files (x86)\Intel\Compiler\11.1\065\bin\intel64\ifortvars_intel64.bat" & & Abaqus Command and Verification don't open. Firsly a dos window appears and...
