Hybrid quasi-Trefftz 3-D finite elements for laminated composite plates

► A new hybrid stress formulation of finite element has been proposed. ► Stress field in point-wise equilibrium is generated by harmonic and orthogonal polynomials. ► Many DOF are involved, but substantial memory and computing time are saved. ► Illustrative applications are given to evaluate displac...
