MATEC Web of Conferences, 2018 The evaluation of the load-carrying capacity of a structure is an important aspect of the structural design. In particular, large seismic events can significantly compromise the performances of structures, or parts of them, due to the formation and ...

Subloading-damage model and its extension to unilateral damage effect [PDF]
, 2019 The elastoplastic constitutive equation with the damage is formulated incorporating the subloading surface model. Further, it is extended to describe the unilateral damage phenomenon by formulating the actual Young’s modulus tensor as the function of the

A densification mechanism to model the mechanical effect of methane hydrates in sandy sediments [PDF]
, 2020 Recent pore‐scale observations and geomechanical investigations suggest the lack of true cohesion in methane hydrate‐bearing sediments (MHBSs) and propose that their mechanical behavior is governed by kinematic constrictions at pore‐scale.

3D nonlinear coupled modelling of geomaterials using the unconventional Subloading Surface approach [PDF]
, 2013 The purpose of the work presented in this thesis is aimed to investigate the nonlinear behaviour of porous media, in detail soils, by means of an unconventional plasticity model named subloading surface.

Generalized subloading surface model with tangential stress rate effect
Journal of applied mechanics, 2005 The traditional elastoplastic constitutive equation, which is inde- pendent of the stress rate component tangential to the yield surface predicts an unrealistically stiff mechanical response for the nonproportional loading proc- ess in which the stress rate has a component tangential to the yield surface.

Multi-material topology optimization based on finite strain subloading surface nonlocal elastoplasticity [PDF]
This study is dedicated to the multi-material topology optimization formulation (MMTO) for finite strain nonlocal elastoplasticity. The subloading surface model is newly incorporated into the primal problem to achieve the gradual change of the ...
