Advances in meshless methods with application to geotechnics (2010)
Presentation / Conference Contribution
Heaney, C., Augarde, C., Deeks, A., Coombs, W., & Crouch, R. (2010, June). Advances in meshless methods with application to geotechnics. Presented at 7th European Conference on Numerical Methods in Geotechnical Engineering, Trondheim, Norway

Finite element methods are well-established for modelling problems in geotechnics involving elasto-plastic constitutive models. However, meshless methods could offer some advantages for problems involving finite deformations as the mesh entanglement...

70-line 3D finite deformation elastoplastic finite-element code (2010)
Presentation / Conference Contribution
Coombs, W., Crouch, R., & Augarde, C. (2010, June). 70-line 3D finite deformation elastoplastic finite-element code. Presented at 7th European Conference on Numerical Methods in Geotechnical Engineering (NUMGE), Trondheim, Norway

Few freeware FE programs offer the capabilities to include 3D finite deformation inelastic continuum analysis; those that do are typically expressed in tens of thousands of lines. This paper offers for the first time compact MATLAB scripts forming a... Read More about 70-line 3D finite deformation elastoplastic finite-element code.

Reuleaux plasticity: analytical backward Euler stress integration and consistent tangent (2010)
Journal Article
Coombs, W., Crouch, R., & Augarde, C. (2010). Reuleaux plasticity: analytical backward Euler stress integration and consistent tangent. Computer Methods in Applied Mechanics and Engineering, 199(25-28), 1733-1743. https://doi.org/10.1016/j.cma.2010.01.017

Analytical backward Euler stress integration is presented for a deviatoric yielding criterion based on a modified Reuleaux triangle. The criterion is applied to a cone model which allows control over the shape of the deviatoric section, independent o...
