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

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

Estimation of Stress Distribution Arising in a Powder Bed during Compaction by FEM considering Anisotropic Parameters [Translated]†

KONA Powder and Particle Journal, 2014
Stress analysis on the compaction of ceramic powder was performed by the finite element method (FEM) to predict the optimum conditions.

Dislocation theory as a 3-dimensional translation gauge theory [PDF]

, 1999
We consider the static elastoplastic theory of dislocations in an elastoplastic material. We use a Yang-Mills type Lagrangian (the teleparallel equivalent of Hilbert-Einstein Lagrangian) and some Lagrangians with anisotropic constitutive laws.

Screw dislocations in the field theory of elastoplasticity [PDF]

, 2002
A (microscopic) static elastoplastic field theory of dislocations with moment and force stresses is considered. The relationship between the moment stress and the Nye tensor is used for the dislocation Lagrangian.

On stress resultant plasticity and viscoplasticity for metal plates [PDF]

, 2008
In this work we derive elastoplastic and elastoviscoplastic finite element formulations for stress resultant bending analysis of thin metal plates. The principle of maximum plastic dissipation is used to obtain the ingredients of the small strain stress ...

Multi-scale computational model for failure analysis of metal frames that includes softening and local buckling [PDF]

, 2010
In this work we present a new modelling paradigm for computing the complete failure of metal frames by combining the stress-resultant beam model and the shell model.

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

Nihon 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.

A multiphase model for reinforced concrete structures considering the concrete cracking

Revista IBRACON de Estruturas e Materiais
Assessing the global behavior of reinforced materials from the individual properties of their components has been the subject of a considerable amount of experimental and theoretical works in the last years.
