Abstract: A new method is proposed for deriving kinematically admissible velocity fields (KAVFs) for three-dimensional upper bound limit analyses in a Tresca material using coordinate transformations. The ...

Abstract: The continuous development of chemical additives facilitated the successful application of the earth pressure balanced (EPB) method in numerous tunnel-excavation projects. One major issue for every successful EPB excavation ...

Abstract: This paper extends previous work reported by Houlsby and Puzrin in 2001 in which a thermomechanical framework was set out for the derivation of rate-dependent plasticity theory with internal variables. A key feature of the ...
