Effect of die parameters and coefficient of friction on equivalent plastic strain during ECAE: modeling and optimization

Cogent Engineering
The present study investigates the effect of die parameters and the coefficient of friction on the equivalent plastic strain (PEEQ) during Equal Channel Angular Extrusion (ECAE). The purpose is to optimize the die parameters to enhance material flow, strain distribution, and overall efficiency of the ECAE process.

Appropriateness of the Hencky Equivalent Strain as the Quantity to Represent the Degree of Severe Plastic Deformation

MATERIALS TRANSACTIONS, 2012
The Hencky strain is a logarithmic strain extended to a three-dimensional analysis. Although Onaka has shown that the Hencky equivalent strain is an appropriate measure of large simple-shear deformation (2010), Jonas et al. (2011) have recently presented a paper claiming that the application of the Hencky strain to large simple-shear deformation is in ...

Tension–torsion fracture experiments—Part I: Experiments and a procedure to evaluate the equivalent plastic strain

International Journal of Solids and Structures, 2013
AbstractDuctile failure experiments on a double notched tube (DNT) specimen subjected to a combination of tensile load and torque that was applied at a fixed ratio is presented. The experimental results extend those in Barsoum and Faleskog (2007a) down to zero stress triaxiality.

Understanding the bending behavior and through-thickness strain distribution during asymmetrical rolling of high-strength aluminium alloy plates

Journal of Materials Research and Technology, 2023
The asymmetric rolling (ASR) process is highly desired to improve the through-thickness deformation/strain uniformity by introducing additional shear strains for uniform through-thickness microstructures and mechanical properties of metallic/alloy plates.
