Dear all,
I notice something in my simulations and I wanted to share it with you. I appreciate if I could have your thoughts on it: In one simulation, when I uniaxially strectch a plate and change the mesh size, I noticed that the nodal stresses and strains remain in the same range. However, once I added an elliptical hole in its center, it seems that as I decrease the mesh size, stress and strain especially at the sharp edges of the ellipse goes up and do not reach to a plateau. My understanding is that it shouldn't be real and in fact should reach to a steady state. Please let me know what you think.
Best, Ali
