Oct 01,2012·Equal Channel Angular Pressing (ECAP) is currently one of the most popular methods for fabricating Ultra-Fine Grained (UFG) materials.In this work,ECAP process has been performed on commercial pure aluminum up to 8 passes by route A.After verification of FEM work,the influences of four die channel angles,three outer corner angles and pass number up to 8 have been analyzed to investigate strain distribution behavior results for this questionHow does small strain stiffness affect plastic hardening?How does small strain stiffness affect plastic hardening?The option of small-strain stiffness is added to the Plastic-Hardening model to take strain-dependency of the modulus into account.With the small-strain formulation soil stiffness behaves nonlinearly with increasing strains.UPDATEDFLAC Constitutive Models US Minneapolis - Itasca results for this questionWhat is kinematic hardening model?What is kinematic hardening model?The kinematic hardening models in ABAQUS are intended to simulate the behavior of metals that are subjected to cyclic loading.These models are typically applied to studies of low-cycle fatigue and ratchetting.4.3.5 Models for metals subjected to cyclic loading

results for this questionWhich is the best description of the plastic hardening model?Which is the best description of the plastic hardening model?The Plastic Hardening (PH) model is a shear and volumetric hardening constitutive model for the simulation of soil behavior.The model is characterized by a hyperbolic stress-strain relationship during axial drained compression (while unlodaing/reloading is elastic) and stress-dependent stiffness described by a power law.FLAC Constitutive Models US Minneapolis - Itasca A theoretical model for the flow behavior of commercial

A semi-mechanistic model for predicting the flow behavior of a typical commercial dual-phase steel containing 20 vol pct of as quenched martensite and varying amounts of retained austenite has been developed in this paper.Assuming that up to 20 vol pct of austenite with different degrees of mechanical stability can be retained as a result of certain thermomechanical treatments in a Analytical modeling of plastic strain induced by deep The objective of this work is to evaluate the equivalent plastic strain levels induced by equal channel angular pressing (ECAP) in an IF-steel billet after one pass at room temperature using the

A Comparison Between Numerical and Analytical Modeling of ECAP M.Rejaeian and M.Aghaie-Khafri* negligible effect on the induced strain. In the upper bound model,strain hardening is not considered and the yield stress or the average of the flow stress is used.Meanwhile,in the FEM (ABAQUS) analysis,the stress and force are calculated inCited by 1Publish Year 2014Author M.Rejaeian,M.Aghaie-KhafriPeople also askHow is the bilinear strain hardening / softening model used?How is the bilinear strain hardening / softening model used?The bilinear strain-hardening/softening ubiquitous-joint model allows representation of material softening and hardening behavior for the matrix and the weak plane based on prescribed variations of the ubiquitous-joint model properties (cohesion,friction,dilation and tensile strength) as functions of deviatoric and tensile plastic strain.FLAC Constitutive Models US Minneapolis - Itasca Cited by 79Publish Year 2012Author F.Djavanroodi,B.Omranpour,M.Ebrahimi,M.Sedighi(PDF) Modeling of Deformation Behavior and Dynamic Strain Modeling of Deformation Behavior and Dynamic Strain Ageing in ECAP.December 2015; Procedia Materials Science 11:418-422; DOI 10.1016/j.mspro.2015.11.019
