Analytic model of the remobilization of pinned glide dislocations: Including dislocation drag from phonon wind

Journal Article Blaschke, Daniel ; Hunter, Abigail ; Preston, Dean Laverne - International Journal of Plasticity

Here, we discuss the effect of a non-constant dislocation drag coefficient on the very high strain rate regime within an analytic model describing mobile-immobile dislocation intersections applicable to fcc polycrystals. Based on previous work on dislocation drag, we estimate its temperature and pressure dependence and its effects on stress–strain rate relations. In the high temperature regime, we show that drag can remain the dominating effect even down to intermediate strain rates. We also discuss the consequences of having a limiting dislocation velocity, a feature which is typically predicted by analytic models of dislocation drag, but which is somewhat under debatemore »« less

Investigation of Ti6Al4V Orthogonal Cutting Numerical Simulations using Different Material Models

Journal Article Alvarez, Roberto ; Domingo, Rosario ; Sebastian, Miguel Angel - AIP Conference Proceedings

Titanium alloys are materials considered as extremely difficult to cut and titanium alloy Ti6Al4V is a reference in machining of titanium. The segmented (saw toothed) chip morphology has attracted great interest in researchers because the understanding of the saw-toothed chip morphology helps to understand the chip formation mechanisms. In this study, the effect of different constitutive models on the saw-toothed chip morphology is examined in machining Ti6Al4V. The paper presents the influence of eight material constitutive modelling in the simulation of segmented chip formation. A critical comparison of outstanding process outputs as cutting force, temperature and measurable parameters for segmentedmore »« less

Local Orthogonal Cutting Method for Computing Medial Curves and Its Biomedical Applications

Journal Article Jiao, Xiangmin ; Einstein, Daniel R ; Dyedov, Volodymyr - SIAM Journal on Scientific Computing, 32(2):947-969

Medial curves have a wide range of applications in geometric modeling and analysis (such as shape matching) and biomedical engineering (such as morphometry and computer assisted surgery). The computation of medial curves poses significant challenges, both in terms of theoretical analysis and practical efficiency and reliability. In this paper, we propose a definition and analysis of medial curves and also describe an efficient and robust method for computing medial curves. Our approach is based on three key concepts: a local orthogonal decomposition of objects into substructures, a differential geometry concept called the interior center of curvature (ICC), and integrated stabilitymore »« less

A microstructure sensitive grain boundary sliding and slip based constitutive model for machining of $$\mathrm{Ti}$$-$$\mathrm{6Al}$$-$$\mathrm{4V}$$

Journal Article Fernandez-Zelaia, Patxi ; Melkote, Shreyes ; Marusich, Troy ; ... - Mechanics of Materials

We report a composite dual phase internal state variable constitutive model was developed for Ti-6Al-4V. The proposed model includes diffusion assisted grain boundary sliding based physics in addition to a traditional slip-based plasticity. Influence of microstructure on the flow stress is introduced via dislocation density and mean grain size internal state variables. The dislocation density evolves according to a physics based law that considers dislocation nucleation and annihilation processes. Grain refinement is driven by dynamic recrystallization, which is modeled phenomenologically. The model is calibrated with uniaxial stress–strain data that ranges between quasi-static and dynamic rates across a wide range ofmore »« less
