Implicit Stress Integration: Return-Mapping and Consistent Tangent Modulus Tensor

2017
Constitutive equations of irreversible deformation, e.g. elastoplastic, viscoelastic and viscoplastic deformations are described in rate forms in which the stress rate and the strain rate are related to each other through the tangent modulus.

The Calculation of Fourth-Rank Constitutive Parameters of Consistent Tangent Modulus and Plastic Modulus in Finite Element Analysis

Advanced Materials Research, 2013
Newton-Raphson method is used in global equilibrium for the numerical solution of elasto-plastic problems. It is necessary to determine the fourth-rank constitutive parameters of consistent tangent modulus in each integration point. Euler backward method and implicit stress integration is applied while constitutive model is implemented into ANSYS ...

Return-Mapping and Consistent Tangent Modulus Tensor

2014
Constitutive equations of irreversible deformation, e.g. elastoplastic, viscoelastic and viscoplastic deformations are described in rate forms in which the stress rate and the strain rate are related to each other through the tangent modulus. Therefore, numerical calculations are executed in their incremental forms by the input of load (stress ...
