I am modelling a 3 point bending test of Asphalt Mixture beam . The beam is modeled as visco-elastic material . After peak load also the material gains strength as it ismodeled as visco elastic but I want to terminated the program once it reaches a yield point how to mention that in ABAQUS .
Please suggest some answers . thank you in advance
One trick is is to do the simulation, control the yield criteria for material, Lets say maximum tensile stress, and monitor the max of tensile stress in your sample. Whenever the max tensile hit that critical yield point, your sample start yielding. You can use whatever criteria you want for yield stress. After this point, your simulation using visco elastic is not valid anymore.
You should be careful that this will be different than the maximum load, because yielding one point does not essentially means yielding the while sample. Typically, we are interested in maximum loading.
