I am doing an explicit analysis, i am trying to model a woven fabric structure. I have to pre-stress the fabric so i have used this option.
*SECTION CONTROLS, RAMP INITIAL STRESS=name
Details from INP file
*Membrane Section, controls = SC, elset=FABRIC, material=FABRIC
*AMPLITUDE, NAME = RampStress, DEFINITION = Smooth Step,time=total time
