DOI: 10.1007/s11600-017-0073-2
Abstract: A constitutive model of rocks subjected to cyclic stress–temperature was proposed. Based on statistical damage theory, the damage constitutive model with Weibull distribution was extended. Influence of model parameters on the stress–strain curve for rock… read more here.

DOI: 10.1016/j.soildyn.2019.105943
Abstract: Abstract The consolidation state imposes great influences on the clay responses to subsequent cyclic loadings. So far most laboratory cyclic tests on clays focused on the isotropically or K0 consolidated conditions, while few considered the… read more here.

DOI: 10.1016/j.trgeo.2021.100580
Abstract: Abstract Cyclic stress is applied to a soil element in the ground when vehicles or trains pass repeatedly on roads and railway tracks. This cyclic stress induced by traffic load gives rise to ground settlement,… read more here.

DOI: 10.1139/cgj-2021-0166
Abstract: A suite of stress-controlled cyclic triaxial tests were performed on frozen fine-grained soils to assess the characteristics of the accumulated and cyclic behaviours under packets of cyclic stress with variable-amplitude. The influence of cyclic stress… read more here.
