Identifier: http://hdl.handle.net/1959.13/936579
Description: In spite of the development of more sophisticated constitutive models for soil, the Mohr-Coulomb yield criterion remains a popular choice for geotechnical analysis due to its simplicity and ease of us... More

Identifier: uon:6207
Description: Yield surfaces for unsaturated soils are inevitably non-convex if the size of the yield surface has to increase with increasing suction. An expanding yield surface with increasing suction is crucial f... More

Identifier: uon:6118
Description: The design of tunnels for roads and railways often utilise separate tunnels to carry traffic in opposite directions. In this paper numerical limit analysis and semi-analytical rigid block techniques a... More
