An extended super/subloading surface model for soft rock considering structure degradation. [PDF]
PLoS ONE, 2021 The strain-softening and dilatancy behavior of soft rock is affected by the loading history and the development of structure. This study regards soft rock as a structured and overconsolidated soil and develops a new elastoplastic model based on the ...

A Constitutive Model for Overconsolidated Structured Soils Using Structural Variable
Shock and Vibration, 2021 Due to the influence of soil structure, structured soils exhibit significantly different mechanical behavior compared to the reconstituted soils having the same material.

Fatigue life assessment of a non-load carrying fillet joint considering the effects of a cyclic plasticity and weld bead shape [PDF]
Fracture and Structural Integrity, 2016 Fatigue life depends strongly on irreversible contributions that accumulate during cyclic loading and unloading of structures. However, the correct identification of the loading path in terms of uniaxial or multi-axial stress states, proportional or non ...

Extended Tangential-Subloading Surface Model for General Loading Behavior of Soils: Application to Nonproportional Loadings [PDF]
Soils and Foundations, 2006 ABSTRACT The conventional elastoplastic model premising that the interior of yield surface is a purely elastic domain is incapable of describing the plastic deformation by the rate of stress inside the yield surface. Thus, it is inapplicable to the description of cyclic loading behavior.

Elastoplastic analysis of mises metal by return-mapping algorithm for extended subloading surface model [PDF]
, 2019 The extended subloading surface model is capable of representing not only monotonic but also cyclic loading behaviors accurately. The various return-mapping methods have been adopted to for the elastoplastic deformation analysis in FEM incorporating the subloading surface model.
