I am trying to simulate the Charpy test using Abaqus, could someone specify the boundary conditions that should be taken and which model should be followed.
Should I use the Johnson Cook's model?
How much time can the simulation take on a 4 core laptop?
I tried reducing the meshing to reduce the simulation time, what effect will it have on the results?
Dear Pearl,
You can employ Johnson-Cook plasticity and define ductile and shear damage to see damage initiation and propagation. For the boundary conditions, better to follow experimental conditions. Probably the specimen should be fixed. Also you may find appropriate mesh size by doing mesh convergence. Better start with larger mesh size and then try to make it finer in order to see how much the result has changed. If there is a huge gap, then you must go for smaller size.
Hope it helps you.
Good luck with your research.
Dear pearl
it is better to used ANSYS LSDYNA or ANSYS AUTODYN instead of ANSYS.
