    different results (bending moments/shear) for different cross sections (FEM)

    When you change cross section you get different results. You must re run the program with the new section and check if the section is sufficient for taking all the forces

    Difference in simulation results by changing element size in LS-DYNA

    Tanks JGard for your response The problem is that I checked this simulation with CONWEP software developed by US army ,for projectile penetration, and I get around 100 m/sec residual velocity. I thought that maybe when I divide elements around the center of the plate I disconnect some of the...

    Difference in simulation results by changing element size in LS-DYNA

    Hi everybody I am trying to simulate a flying steel pipe with it's axis perpendicular to the center of a 2x2 m' steel plate (50 grad steel) 30 mm thick. the pipe is 12 c"m diameter and about 6 mm thickness A36 steel with a velocity of 340 m/sec . The pipe and the plate are first modeled as...
