Does metal to metal joining by FSW really occur so as to withstand loads in abaqus?

I am curious to know if metal bonding by welding (FSW) can really be simulated in Abaqus or not. I have read many papers wherein people simulate the FSW process only and study the temperature and...

Why do certain elements become grey in color (zero stress) when I try to simulate friction stir welding between two plates in abaqus?

I'm trying to simulate friction stir welding using CEL method in Abaqus. After meshing both the Lagrangian instances and the Eulerian domain, when I run the simulation, certain elements on the...

How to quantify the energy into and parallel to a plate in Comsol?

I'm working on a problem involving a fluid impact on the forehead. I understand some waves ( Lamb or Rayleigh) will be generated due to the impact force. I'd like to simulate the event in Comsol...

What failure model should I use for modelling a bullet impact into a polycarbonate plate?

I'm trying a simulation of a bullet impact into polycarbonate plate of thickness 5 mm. For metals, the Johnson Cook parameters are readily available. But, I'd like to know where to get the same...

What value should be given for 'displacement at failure' in abaqus?

I am trying to simulate a bullet impact into Aluminum-1100 plate which is 5mm thick. The conical bullet's velocity is 375 m/s and I modeled it as a rigid body. I am not sure what value for the...
