Hi

I am new to abaqus . I need help for simulation of low velocity impact on structure. I am trying to run Problem mentioned in Book by Goldsmith , where a steel ball of 10mm radius make impact on simply supported beam (10mmx10mmx153.5mm). velocity of the ball is 10mm/s.Both ball and beam are made of steel material . I have defined general surface based contact between steel ball and upper surface of beam . I am getting relatively low value of peak contact force 0.35N inplace of 5N .Can any one help me with this
