Research on elasto-plastic viscous fatigue constitutive model of jointed rock
Rock and Soil Mechanics, 2021 The jointed rock mass exhibits an obviously instantaneous plastic strain under fatigue loading, and thus it is imperative to establish a fatigue constitutive model of jointed rock considering instantaneous plasticity.

Strain rate dependency of dislocation plasticity [PDF]
Nature Communications, 2021 AbstractDislocation glide is a general deformation mode, governing the strength of metals. Via discrete dislocation dynamics and molecular dynamics simulations, we investigate the strain rate and dislocation density dependence of the strength of bulk copper and aluminum single crystals.

Importance Assessment of Structural Members Based on Elastic-Plastic Strain Energy
Advances in Materials Science and Engineering, 2019 Based on the elastic analysis, the existing methods of the importance assessment of structural members can only reflect the structural elastic behavior. To understand the plasticity and stiffness degradation of the structure, the present study proposes a

Plastic flow behavior of twinning induced plasticity steel from low to warm temperatures
Journal of Materials Research and Technology, 2020 This work investigates the tensile behavior of twinning induced plasticity (TWIP) steel under room to warm temperatures. Stress-strain flow curves have been obtained from steady-state uniaxial tensile tests performed at different temperatures, that is ...

Modeling of Personalized Anatomy Using Plastic Strains [PDF]
ACM Transactions on Graphics, 2021 We present a method for modeling solid objects undergoing large spatially varying and/or anisotropic strains, and use it to reconstruct human anatomy from medical images. Our novel shape deformation method uses plastic strains and the finite element method to successfully model shapes undergoing large and/or anisotropic strains, specified by sparse ...

Modeling strain rate sensitivity and high temperature deformation of Mg-3Al-1Zn alloy
Journal of Magnesium and Alloys, 2019 Increasing the plastic deformation temperature of Mg alloys results in higher strain rate sensitivity, easier activation of secondary slip modes, and impeded twinning. In this study, the strain rate sensitivity is estimated for each deformation mode, and

Correlations of strain and plasticity in a flowing foam [PDF]
EPL (Europhysics Letters), 2015 Via simulations of flowing foam, we connect the high and intermediate density regimes of complex fluid flows into a consistent microscopic picture of deformation. While at and above the jamming transition, elastic correlations lead to strong spatial organization of the flow field, below jamming, the slowly diminishing elastic correlation length leads ...
