    Is it correct to change the mass density in some explicit analysis?

    I have the same problem with my simulation. When I ran the simulation with the mass density 7.8e-9 my simulation doesn't complete. How did you resolve this problem?

    Dimension problem in Abaqus?

    Dear all, I am simulating a shot impact onto a circular steel plate. The shot is defined as a rigid sphere with initial velocity 75 m/s. The SI (mm) is used throughout the simulation and the following material data. Material, name=steel *Density 7.8e-09, *Elastic 210000., 0.3 *Plastic...

    Multiple shot impacts, what load type to use?

    Thank you for your suggestions Rob. My output odb file is exceeding a few hundred GB. Is there a way of reducing the file size by change the History or Field Output interval?

    Multiple shot impacts, what load type to use?

    Hi everyone, I am trying to simulate the shot peening process in Abaqus. Large number of shots (approx 10 000 shots) impacting on a metal surface and creating compressive residual stresses.The shot-shot interaction in the shot peening process is simulated in a different application and I would...

    Single shot impact in Abaqus

    Hi Rob, Thanks for your reply. I couldn't find any material test data and will use the material properties that is available on Matweb. Many Abaqus examples use fixed displacements for loading and unloading. In terms of measuring the rebounding velocity, what method would be most appropriate...

    Single shot impact in Abaqus

    Hi I would like to simulate a single steel shot impact on a steel metal surface and measure the residual stresses and the rebounding velocity of the shot after impact (coefficient of restitution). Simulation should be in 3D. The initial velocity of the shots are about 70 m/s. Is high stress...
