Regularized BE formulations for the analysis of fracture in thin plates
Regularized BE formulations for the analysis of fracture in thin plates
- International Journal of Fracture, 84, p.351-366, 1997 .
A boundary integral formulation for the analysis of cracks in thin Kirchhoff plates is presented. The numerical solution of the relevant equations is addressed following three different approaches: two single integration methodologies initially introduced for 2D elastic solids are here reformulated, compared with a third (Galerkin)double integration approach and extended to the analysis of cracks in thin plates exploiting an analogy with 2D elastic fracture mechanics. Comparative numerical testing, in terms of stress intensity factors, is performed with reference to straight and curved cracks in unbounded domains.
