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…

Abstract: Abstract The long-term serviceability of infrastructures in cold regions is inevitably affected by such dynamic loads in practical works as earthquake loading and vehicle loading. In order to study the deformation characteristics of frozen soil…

Abstract: Abstract The interaction between hydrogen and cyclic stress were investigated on E690 steel by hydrogen pre-charging under cyclic loadings of various peak stresses, and hydrogen determination, tensile tests and observation on microstructures. Results show that…

Abstract: Abstract Total strain-controlled low cycle fatigue tests were conducted on the newly designed nickel-base superalloy M951G under different testing conditions; the relationship among cyclic stress responses, microstructural degradations, deformation mechanisms and testing conditions has been…

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…

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,…

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…
