DOI: 10.1016/j.ijpvp.2018.12.003
Abstract: Abstract This paper aims to investigate whether creep strain accumulated at different strain rates is equally damaging. Previous research has suggested that creep strain is more damaging when accumulated more slowly in creep of notched… read more here.

DOI: 10.1016/j.ijpvp.2021.104500
Abstract: Abstract A micromechanical crystal plasticity self-consistent model (SCM) is used to analyse loading histories in 316H stainless steel. SCM predictions on changes in cyclic and creep properties are compared to analyses via the R5 assessment… read more here.

DOI: 10.1139/cgj-2022-0014
Abstract: To understand the time-dependent fracture behaviour of hard rock in the excavation damage zone (EDZ), a series of stress paths are designed to obtain the same initial damage extent induced by excavation. The influence of… read more here.
