A Mesh Objective Algorithm for Modeling Mode-I Cracks Using a Standard Finite Element Formulation
A computationally efficient mesh objective algorithm for modeling mode-I cracks is developed and implemented within a standard finite element formulation. The algorithm applies the crack opening displacements across the standard nodal degrees of freedom that is consistent with formalism of the …

Constitutive Modelling of Shear Localisation in Saturated Dilative Sand
… movements at grain scale without extreme mesh refinement. This thesis aims to evaluate the capabilities of the finite element method and existing material models to identify the onset and propagation of localisation in dilatant hardening materials. Then constitutive relations are upgraded …
