Justification of fracture criteria for salt rocks

open access: yesFracture and Structural Integrity, 2022
The study of salt rocks deformation and fracture processes is an essential part of mining parameters justification for mineral salt deposits. The results of uniaxial compression tests on large salt rock specimens are presented as a loading curve and ...

Heredity and evolution laws of flatness defects in steel strip temper rolling processes

open access: yes工程科学学报, 2015
Three-dimensional temper rolling processes are simulated by nonlinear elastoplastic finite element software called ABAQUS. In this simulation, the initial flatness defects of steel strips are modeled by the temperature field, and the adjustment effect of

About the Memory of Transformation-Induced Plasticity in 35NCD16 Carbon Steel Subjected to Various Thermomechanical Histories

open access: yesMetals, 2021
This study deals with Transformation-Induced Plasticity (TRIP) observed in the martensitic transformation of 35NCD16 ferritic steel. In this study, TRIP tests were carried out for two different cases: First, after only free dilatometric (FD) tests, which

Analytical and Numerical Methods for Finite-Strain Elastoplasticity

open access: yes, 2021
An important class of finite-strain elastoplasticity is based on the multiplicative decomposition of the strain tensor $F=F_el F_pl$ and hence leads to complex geometric nonlinearities. This survey describes recent advances on the analytical treatment of

Anisotropic Antiplane Elastoplastic Problem [PDF]

open access: yesJournal of Siberian Federal University. Mathematics & Physics, 2020
In this work we solve an anisotropic antiplane elastoplastic problem about stress state in a body weakened by a hole bounded by a piecewise-smooth contour. We give the conservation laws which allowed us to reduce calculations of stress components to a contour integral over the contour of the hole.

Dimension reduction for elastoplastic rods and homogenization of elastoplastic lattices

open access: yes, 2021
We derive effective equations for periodic lattices of linearly elastoplastic rods in the limit of both infinitesimal periodicity and infinitesimal relative width of the rods. For this derivation we use the method of evolutionary Γ-convergence for quadratic rate-independent systems.

Extension of subloading surface model for accurate prediction of elastoplastic deformation behavior of metals with cyclic softening

open access: yesNihon Kikai Gakkai ronbunshu, 2014
The subloading surface model has been formulated and applied to the prediction of cyclic loading behavior of metals. However, the existing formulation of this model is limited to metals exhibiting only the cyclic hardening.

Foundations of elastoplasticity subloading surface model

open access: yes, 2017
This book is the standard text book of elastoplasticity in which the elastoplasticity theory is comprehensively described from the conventional theory for the monotonic loading to the unconventional theory for the cyclic loading behavior. Explanations of

Qualitative and Numerical Analysis of Quasi-Static Problems in Elastoplasticity [PDF]

open access: yes, 1997
The quasi-static problem of elastoplasticity with combined kinematic-isotropic hardening is formulated as a time-dependent variational inequality (VI) of the mixed kind; that is, it is an inequality involving a nondifferentiable functional and is imposed
