mimic

Hi guys,



I'm working on an ABAQUS extension/plug-in of a sort and I'd like to replicate results for a single 4-node plane stress element produced by the ABAQUS incremental/nonlinear static solver.



I assumed the relationship is:

_t[K] {Δx} = _t+Δt {P} - _t{F}



This is how I went to obtain these values:

_t [K] - element stiffness - by using *ELEMENT MATRIX OUTPUT
