This paper presents a three-dimensional structural optimisation approach based on the boundary element and level set methods. The structural geometry is implicitly represented with the level set method, which evolves an initial structural model towar...

Computer aided design of mechanical components is an iterative process that often involves multiple stress analysis runs; this can be time consuming and expensive. Significant efficiency improvements can be made by increasing interactivity at the con...

Presentation / Conference Contribution
Hattori, G., Alatawi, I., & Trevelyan, J. (2015, April). A direct SIF approach for anisotropic materials using the boundary element method. Presented at ACME 2015., Swansea, Wales

Recently developments in numerical methods such as the Extended Finite Element Method (X-FEM) and the Extended Boundary Element Method (X-BEM) have significantly improved the accuracy in linear elastic fracture mechanics (LEFM) problems. Nevertheless... Read More about A direct SIF approach for anisotropic materials using the boundary element method.

We introduce an alternative method in computational fracture mechanics to evaluate Stress Intensity Factors (SIFs) directly using the Extended Dual Boundary Element Method (XBEM) for 2D problems. Like other enrichment approaches, the new approach is... Read More about A direct evaluation of stress intensity factors using the Extended Dual Boundary Element Method.

A boundary element method (BEM), based on non-uniform rational B-splines (NURBS), is used to find solutions to three-dimensional wave scattering problems governed by the Helmholtz equation. The method is extended in a partition-of-unity sense, multip... Read More about Extended isogeometric boundary element method (XIBEM) for three-dimensional medium-wave acoustic scattering problems.
