Dears

i am trying to simulate friction stir spot welding process, it is process very similar to drilling process but with different tool, i need to know the effect of process time on the heat generated or on the contact temp.

explicit dynamics is not suitable for process with long time, almost 1 sec process time wll tank about 4 days of solving

also i am trying LS DYNA but i cannot find the material removal feature in it (erosion control -- on material failure)

if some body could help
