RESUMO

Here, static and dynamic analysis of a number of anisotropic problems using the boundary element method are presented. The formulation used is developed fram the elastostatic fundamental solutions and the domain integraIs due to inertial terms are transformed into boundary integraIs by using the dual recipracity method. Application is made to the calculation of deflections in anisotrapic plates, to the dynamic analysis of orthotrapic plates and to the analysis of anisotropic and composite laminar plates under harmonic loads. Numerical results are presented for quasi-isotropic, orthotropic and anisotrapic problems. The influence of number of internal nodes and number of boundary elements on the accuracy of the results is analyzed. The results are compared with other results fram the literature showing good agreement
