HYBRID QUASI-TREFFTZ FINITE ELEMENTS HAVE BEEN APPLIED WITH SUCCESS TO THE ANALYSIS OF LAMINATED PLATES. TWO INDEPENDENT FIELDS ARE APPROXIMATED BY LINEARLY INDEPENDENT, HIERARCHICAL POLYNOMIALS: THE STRESS BASIS IN THE DOMAIN, ADAPTED FROM PAPKOVITCH-NEUBER SOLUTION OF NAVIER EQUATIONS, AND THE DISPLACEMENT BASIS, DEFINED ON ELEMENT SURFACE. THE STRESS FIELD THAT SATISFIES THE TREFFTZ CONSTRAINT A PRIORI FOR ISOTROPIC MATERIAL IS ADAPTED FOR ORTHOTROPIC MATERIALS, WHICH LEADS TO THE TERM ÂQUASIÂ. IN THIS WORK, THE HEXAHEDRAL HYBRID QUASI-TREFFTZ STRESS ELEMENT IS APPLIED TO THE MODELING OF NONSYMMETRIC LAMINATES AND LAMINATED COMPOSITE PLATES WITH GEOMETRIC DISCONTI-NUITIES. THE HIERARCHICAL P-REFINEMENT IS EXPLOITED.
