Simulation of NTS contact problem with non-Penetration condition

Simulation of NTS contact problem with non-Penetration condition

Simulation of NTS contact problem with non-Penetration condition

(OP)
Hey,

I'm currently working on Project where i should simulate a NTS contact Problem for two simple beams
with non-Penetration condition 
and my element is a quadratic tetrahedron.
However, i have two surfaces one SLAVE and the other one MASTER and i have established all the detection numbering of my Points for both surfaces master and slave so Pm ,ps1,ps2,ps3.

My Problem indeed is to implement this both surfaces and i have no idea how to construct my shape function and then to go Forward for K Matrix.
if any one could just give me some tips how should i see the Problem ?, what is the methodology of the Resolution ??

Thank you

Y
