Viscoplastic deformation analysis for spheroidal graphite cast iron by subloading-overstress model
Nihon Kikai Gakkai ronbunshu, 2020 The time-dependent elastoplastic deformation behavior, i.e. viscoplastic deformation behavior, is observed in solids and structures subjected to high temperature under monotonic and cyclic loadings.

Application of the multi-laminate sub-loading surface model in the simulation of a pipe-jacking operation [PDF]
Numerical Methods in Civil Engineering, 2014 In this paper a constitutive model formulated in the framework of multi-laminate models is applied to analyze pipe-jacking processes. The multi-laminate -based models consider various integration planes to formulate the stress-strain relationship.

Nihon Kikai Gakkai ronbunshu, 2014 The subloading surface model possesses the automatic controlling function to pull back the stress to the yield surface. However, this function is not concerned with the subyield state, i.e.

Dilatancy relation for overconsolidated clay [PDF]
, 2017 A distinct feature of overconsolidated (OC) clays is that their dilatancy behavior is dependent on the degree of overconsolidation. Typically, a heavily OC clay shows volume expansion, whereas a lightly OC clay exhibits volume contraction when subjected ...

A subloading surface clay and sand model
, 2022 The mechanical response of natural soils is characterized by a narrow elastic domain, a smooth transition between elastic to elasto-plastic regime, and hysteretic behaviour during cyclic loading. These realistic features can be efficiently intro-duced into an existing constitutive model by reformulating it in the framework of subloading surface ...
