Array, so basically, the guass points itself are a function of the displacements of the nodes, therefore while carrying out the integration to assemble the element stiffness matrices and to have the required equilibirum in the solution, it all drops down to having only nodal displacements of the whole model, as the unkowns. Is that correct, sir?nStress and strain are not solved for, but the equations that have stress and strain terms in them were included during the assembly phase of the stiffness matrix, before the solving started. These strain and stress will also simplify to only having constants and unkown nodal displacements, right?n
