Hi All,

 I want experts suggestion regarding the constitutive model for woven fabrics.

Hi,
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. 

*AMPLITUDE, NAME=name
*SECTION CONTROLS, RAMP INITIAL STRESS=name

Details from INP file

*Membrane Section, controls = SC, elset=FABRIC, material=FABRIC
0.5,

*AMPLITUDE, NAME = RampStress, DEFINITION = Smooth Step,time=total time
0.0, 0.0, 0.0025, 1.0, 1.0, 1.0
