LARGE DEFLECTION OF COMPOSITE LAMINATE THIN PLATES BY THE BOUNDARY ELEMENT METHOD

Silveira, L. C.; Albuquerque, E. L.

Full Article:

Boundary-integral equations for large deflections of thin plates are presented. Quadratic boundary elements are used to discretise the boundary. Domain integrals that arise from non-linear terms are transformed into boundary integrals using the radial integration method. As a result, the obtained formulation does not demand domain discretization. For the solution of the non-linear system, the total incremental method is used. A numerical example is presented and comparisons with other numerical results are made to demonstrate the accuracy of the proposed method. The formulation illustrates the adaptability of the boundary element methods to non-linear problems.
