I have been simulating low velocity impact test on concrete brick using concrete damage plasticity model. The impactor is penetrating the concrete brick instead of forming crack on the brick upon impact. What migt be the issue here? I am using dunamic/explicit solver. Below I have attached the picture of simulation. Please help me figure this out as i am new to learning Abaqus. Thank you
Abdellah Benchekkour, I am using surface-to-surface contact. What would you recommend?
It seems that with some porous type of geometry you are trying to carry out impact analysis. and You might have define contact using surface of projectile and top surface of porous geometry.
1. Try to use general contact (explicit), if it is a porous geometry
2. check the type of element used, it should be explicit
3. type of analysis : Explicit
4. ensure defining contact property in the model
5. In field output select the right output such as DAMAGEC/DAMAGET
6. For every material you need to define two strength curves (compression and tension) and two damage curves behaviour (for compression and tension) so total 4 curves for each material where material is defined by Concrete damage plasticity
i hope this may help in your work
best wishes
