I want to develop a material model where there is a non-linear variation in elasticity of the material depending on the stress applied.
But the non linearity of the system is not pre decided... It is determined by the stress applied. Iterations are performed until the elasticity( Resilience) stabilises
Hello, Arjun! At any case, the calculation is carried out in ANSYS only after setting nonlinear material properties, such as a table "strain-stress".
Can you suggest me any idea how i could model it in ansys?
The non linearity is determined by the stress applied.
But E value variation in my model is derived by the model itself. The E value is redetermined by the stress applied. The value is iterated until the E value converges.
I am modelling a flexible pavement. The pavement has three layers. The middle layer is granular and has a non linear E value. That is E value of the layer varies in the coordinates of the layer.
So for that I have meshed the layer with a seed E value. Later for a load,the stress at each finite element is determined. This stress value is used to determine the E using K-Theta Model( Fairly accepted model), where E is a function of Theta. Then Each element is allocated the newly determined E value. The process is iterated until E Value converges.
Can you please suggest any ideas to perform the simulation?
Hello Arjun
have u got your answer...actually i m also having same problem while modelling flexible pavement...If yes then plz help
