A systematic mathematical approach is developed in the context of uniaxial cyclic ratcheting for the

parameter determination of the decomposed Chaboche hardening rule. This is achieved by deriving

the relation ...

Abstract— Recent technologies provide new opportunities for the construction of heterogeneous vessels with adaptable material compositions called Functionally Graded Materials (FGM). In order to benefit the damage tolerance ...

In the realm of multi-axial ratcheting, a step by step mathematical approach is developed for the

parameter determination of decomposed kinematic hardening rules. For this purpose, key

characteristics are mathematically derived...

using nonlinear isotropic/kinematic hardening model. The results of the

numerical simulations were compared to experimental data. The results

demonstrated that the ratcheting response of plates with circular cutouts

could be numerically...

crucial role in increasing the local plastic deformation. Numerical simulation was done by ABAQUS software using nonlinear isotropic/kinematic hardening model. Material parameters of hardening model were attained from several stabilized cycles of flat...

to the multicomponent form of the nonlinear kinematic hardening in order to provide a comparison for

the suggested technique. Moreover, a consistent tangent operator for the exponential-based integration strategy and also for the classical

forward Euler...
