I am applying periodic boundary conditions on the matrix phase (without inserting any fibers into it) and calculating the effective Young's modulus in X direction. In the property module, Youngs Modulus as 3 GPa and Poisson's ratio as 0.33.
After running the simulation by applying a multi-point linear constraint equation, I am getting the Effective Youngs modulus in the X direction as 4.379GPa. But how can Young's modulus be more than 3GPa, I mean it should come near about 3GPa.
It's wrong!!!! If you have only one phase, effective properties are almost equal to input mechanical properties.
Share an image of your model or your code, maybe I could help you.
Thank You Sir for your response.
I am sending the CAE and JNL files where I have manually applied the Periodic boundary condition on the coarser mesh. Kindly check it.
I can't open these files because I have Abaqus 6.14 on my system. you can see chapter 8 of this book "Finite Element Analysis of Composite Materials Using Abaqus, Ever J. Barbero" and these link:
