Modelling the Structure and Anisotropy of London Clay Using the SA_BRICK Model

Applied Sciences, 2023
Several constitutive models had been developed by other researchers to cover the main features of mechanical behaviour of natural overconsolidated clays, such as the nonlinear stress–strain response at small and large strains, and the recent stress ...

Influence of Hardening on the Cyclic Plastic Zone Around Crack Tip in Pure Copper CT Specimens [PDF]

Journal of Stress Analysis, 2018
Under cyclic loading, the plastic zone becomes complicated during unloading. The energy-absorbing cyclic plastic zone is a stimulant for crack growth and can be a criterion for determining the damage around the fatigue crack tip.

Effect of the yield surface evolution on the earing defect prediction

Revista de Metalurgia, 2023
Although the prediction of earing in the cup drawing process is considerably related to the yield surface shape, the yield surface evolution is also essential for the final ear form.

Effects of the Unified Viscoplastic Formulation and Temperature Terms on the Thermomechanical Behavior of Soldering Materials [PDF]

, 2012
Solder materials are critical packaging compounds and due to usually weakest melting temperature among packaging constitutive materials, thus, they are frequently subjected to a multitude of physical phenomena: creep, fatigue and combined hardening ...

Stress integration of the Drucker-Prager material model with kinematic hardening [PDF]

Theoretical and Applied Mechanics, 2015
This paper presents a method for implicit stress integration of the Drucker-Prager material model with kinematic hardening. The stress integration of the material model is conducted using the incremental plasticity method, while the kinematic ...

Plastic deformation modelling of tempered martensite steel block structure by a nonlocal crystal plasticity model

Theoretical and Applied Mechanics Letters, 2014
The plastic deformations of tempered martensite steel representative volume elements with different martensite block structures have been investigated by using a nonlocal crystal plasticity model which considers isotropic and kinematic hardening produced

Evaluating the effectiveness of combined hardening models to determine the behavior of a plate with a hole under combined loadings

European Mechanical Science, 2022
Geometrical discontinuities in a material such as holes and notches on machine elements are called as critical regions due to the stress concentrations. They are the potential failure initiation locations Therefore, researchers put significant effort on ...
