How do I specify contact between fibre and matrix in LS Dyna?

I am doing a Mesoscale simulation for tensile test of CFRP. On application of load there is no load sharing between fibre and matrix since I didn't specify contact between the two. How can I do that?

How to obtain the strain-rate dependent material properties of CFRP composite using strain-rate dependent strength of resin?

I have results for dynamic strength of resin at a higher strain rate. I want to use these results to evaluate material properties of CFRP at the higher strain rate assuming fiber strength isn't...

How to implement viscoelastic behaviour of resin in LS DYNA for impact loading?

I have stress strain curve of resin (attached as image) at varying strain rates. I want to implement this strain rate dependent behaviour of resin for impact simulation of a CFRP tank in LS DYNA.

On application of y-direction pressure why does my result show x and z direction displacement(large)?

I have a 3D macro scale model of half pressure vessel. I am applying pressure on the top surface in y direction while fixing the bottom surface in y direction. The simulation result indicate that...
