POST-PROCESSING OF ANISOTROPIC LAMINATES IN DYNAMIC PROBLEMS MODELED USING GENERALIZED FINITE ELEMENT METHOD

Resumo

The paper presents a post-processing method to be applied in results obtained from dynamic analysis in
thin laminated structures. The problems are modeled using the Generalized Finite Element Model (GFEM) and
are based on first order shear deformation theory. The main goal of this work is to analyze the effects of the inertial
and body forces on the results obtained from the stress and displacement recovery method. The method relies on
values obtained from GFEM which are next are applied to the general local constitutive, kinematic and motion
equations. GFEM are integrated and the values of the transverse stresses are then corrected using stress-strain
relations. Also, all components of displacements can be recovered. These new corrected displacement and stress
values are then compared with results obtained from analytical and numerical solutions for validation.
