Hi All, I'm presently working on modelling of guided ultrasonic wave scattering at defect using Abaqus/CAE. Can anyone help me with some tutorial materials on modelling of crack or notch in a through-hole of a plate? Warm Rgrds. Jo Ukpai |

Bloch-periodic boundary conditions in classical and enriched FEM
In the attached paper (accepted for publication), we present enriched FE formulations to impose Bloch-periodic boundary conditions. Bloch-periodic BCs arise in the description of wave-like phenomena in periodic media: periodic composites, Schrodinger equation in quantum mechanics, photonic band-gap materials, etc. For a perspective, see the J-Club on elastodynamic bandgaps and metamaterials that was organized by Biswajit Banerjee
Meshfree/Meshless methods(MLPG)
I am using Meshless Petrov-Galerkin Method(MLPG) for non-rectangular domains. There is a flexibility of using any shape for weight function and also for local quadrature domain. Here in my case case weight function domain and local quadrature domains are same.
I want to know that , for non-rectangular domains,how the different shapes of weight functions (specially circular or rectangular) will affect accuracy of the result ?
