    getting the same results while mesh size is changing-UMAT

    Hi All, I am modelling damage and plasticity in UMAT, ABAQUS. My main question is that I am wondering why my results like yield stress , ultimate stress will be constant as I have changed the mesh size? For example for mesh size =0.2 and mesh size equal 0.00002. I would say I model damage and...

    changing density with position

    Hi all http://www.eng-tips.com/viewthread.cfm?qid=407667 Hi All, I am going to model density that is changing through the thickness for graded plates. Before, I wrote UMAT to model variation of elastic modulus through the thickness and I solved my bending problem. But at this moments I want to...

    Hi All, I am going to model densit

    Hi All, I am going to model density that is changing through the thickness for graded plates. Before, I wrote UMAT to model variation of elastic modulus through the thickness and I solved my bending problem. But at this moments I want to add density to solve vibration as well. I dont know how...
