// the question is whether this function should exist ?
// if yes the element details will be hidden.
// good idea also should be existence of element::GiveBmatrixOfLayer
// and computing strains here - but first idea looks better
// but treating of geometric non-linearities may become more complicated
// another approach - use several functions with assumed kinematic constraints
// resolve current layer z-coordinate

fiberMat->giveRealStressVector_Fiber(reducedFiberStress, fiberGp, fiberStrain, tStep);
// perform integration
// 1) membrane terms N, Qz, Qy
answer.at(1) += reducedFiberStress.at(1) * fiberWidth * fiberThick;
