Reloading in barodesy employing the asymptotic state boundary surface
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 45, Issue 14, Page 2113-2129, 10 October 2021., 2021 Abstract The reloading behaviour of the soil is dominated by effects of the recent deformation history as well as by the overall stress history, indicated by overconsolidation. The stiffness of an overconsolidated soil is higher than the stiffness of normally consolidated soil.

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 Train‐induced vibration is increasingly attracting people’s concern nowadays. In the coastal areas, many metro tunnels are built in the soft deposits, so the train‐induced vibration effect is more serious. Nevertheless, the existing research studies mainly focus on the dynamic responses in the tunnel or on the ground surface while vibration ...

A subloading surface clay and sand model [PDF]
, 2023 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.

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.

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 ...

Dynamic constitutive model for subloading surface of rock materials considering rate effect
Yantu gongcheng xuebao, 2018 In order to reflect the characteristics of the hysteresis loop under cyclic loading and the rate effect under dynamic loading of the rock materials, firstly, based on the theory of subloading surface, the stress-path model for the subloading surface ...

Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020 To better control the strength and deformation of the roadbed, a constitutive model of rockfill was established based on property‐dependent plastic potential theory for geomaterials. The effect of the particle gradation on the anisotropy was described in the model.
