Error with material failing in Non-Linear Analysis - Please help!
I am using the newer versions of ANSYS (19.1) and I have found the options to input the values in engineering data for the Menetrey William model.
The following are the values I have inputted for Non-Linear Concrete.
However, when I try to run the program, I keep getting error about how an element is failing. I am modelling the following pull-out test and using symmetry to only analyse half of it:
I have also used contact sizing and therefore the mesh for concrete near the rebar as well as the rebar has been set to 1mm (This is the smallest I could go for a 150mm diameter concrete cylinder with a height of 170mm on the Academic Version of Ansys).
I have applied the following analysis settings, boundary conditions and loading (force is corresponding to the yield strength of the bar i.e. 541MPa but only half of the load is applied due to symmetry):
I had to change it to unsymmetric solver type before as it would just won't run if I left it on program controlled.
I have attached the archive file to this post if someone is kind enough to take a look to see if I made any errors. I currently haven't defined a bilinear hardening model for steel as I was having errors running it when I defined it. But since I am only applying the load until yield strength, wouldn't specifying the yield strength be sufficient because it is still linear?
If someone could please help, it would be wonderful - it is for my thesis and I am new to this software!
