Micro-twinning initiation and evolution models are incorporated in the single crystal AE-CP finite element models for manifesting tension compression asymmetry.
Models were estimated using full information maximum likelihood (FIML) estimation with raw ordinal data, which included zygosity, twin age, and initiation and progression information relating to conduct problems and/or marijuana use for each twin.
Our findings in adolescents, together with those of several previous adult twin studies, indicate that initiation and progression of substance use are partially independent liabilities (particularly in the case of alcohol).
Upon establishing the γ surfaces from density functional theory, critical stresses for the initiation of slip, twin and post-yield twin-slip interactions are computed within a Peierls-Nabarro modeling framework.
The double-differentiation method was employed to detect the initiation of twinning as well as of dynamic recrystallization.
This paper describes the use of synchrotron X-ray diffraction to map crack tip strain field evolution and initiation of twinning under applied load in a fatigue pre-cracked zirconium alloy.
The study revealed the twin role of Mg in initiation and in continuation of infiltration.
The current study investigates the effect of twin density on the crack initiation toughness and stable fatigue crack propagation characteristics of NT Cu.
Some twin studies suggest that substance initiation and dependence are part of a complex, two-stage process and that some genetic influences are stage-specific, acting on either the transition from abstinence to initiation, or on the transition from use to dependence.
In the high temperature interval from 100too 250 °C the SFE ranges from 29 to 44 mJ m−2 and the initiation of mechanical twinning is delayed leading to reduced work-hardening in the intermediate and final stages of strain-hardening.
