Texture development and hardening characteristics of steel

Crystallographic texture development and hardening characteristics of a hot-rolled,low-carbon steel sheet due to cold rolling were investigated by idealizing the cold rolling process as plane-strain compression.The starting anisotropy of the test material was characterized by examination of the grain structure by optical microscopy and the preferred crystal orientation distribution by x-ray Stress and strain control via level set topology optimizationThis paper presents a level set topology optimization method for manipulation of stress and strain integral functions in a prescribed region (herein called sub-structure) of a linear elastic domain.Stress and Strain GeologyWhen stress causes a material to change shape,it has undergone strain ordeformation.Deformed rocks are common in geologically active areas.A rocks response to stress depends on the rock type,the surrounding temperature,and pressure conditions the rock is under,the length of time the rock is under stress,and the type of stress.
