Composite Simulation

Hi

I am currently modeling a quasi static tensile test for a composite.  I have a dog-bone shaped sample in which one end is fixed and a constant rate of 1.5 mm/min is applied to the other end. I am using LS-Dyna solver. I used Mat 54-55 material card. I wanted to make sure whether my approach is correct or not. Enclosed is my  hm file. I have used consistent units thru out (tonnes, GPa, mm, ms - hopefully it is correct). Also I defined a prescribed displacement curve through out the duration of the test.  Any help on this is much appreciated
