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 ...

Application of a Stress-Fractional Model for Capturing the Stress-Strain Behavior of Granular Soils
Advances in Civil Engineering, 2021 Granular soils usually serve as the filler material in geotechnical engineering. This study presents the development and application of a stress-fractional model for granular soils with different initial material states.

Modified unified critical state model for soils considering over-consolidation and cyclic loading behaviours. [PDF]
Sci Rep, 2023 This paper presents a modified unified critical state model to predict the mechanical responses of both clays and sands under over-consolidation and cyclic loading conditions on the basis of clay and sand model (CASM), which is named as CASM-kII. Through

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 ...
