MODELING OF FGM IN ABAQUS
hello every one,
i am Ravitej, doing my Mtech at IIT kanpur, India. Now, i am working on FGM( funtionally Graded Materails). Can i model the FGM as a layered specimen with the youngs modulus varying according to layers. is there any special elements in abaqus, so that we can assign property variation along the thickness.
Problem that i had faced with the layerd model is
1) stress is not continous at the interface of layers, then how can we believe that the solution obtained is correct
2) what could be the youngs modulus at the interface, will it be average of two adjacent layers
please guide me in this aspect to model the FGM correctly..
