Measurement of Residual Stress in the Brain. [PDF]

J Biomech Eng
ABSTRACT Mechanical stress in brain tissue is an important feature of the brain, likely to play key roles in brain development and brain injury. Here, we characterize residual stresses in grey matter and white matter from the deformed shape of tissue cylinders extracted from the brain using a biopsy needle and imaged with high ...

Residual Stresses in Glasses [PDF]

Physical Review Letters, 2013
The history dependence of the glasses formed from flow-melted steady states by a sudden cessation of the shear rate $\dotγ$ is studied in colloidal suspensions, by molecular dynamics simulations, and mode-coupling theory. In an ideal glass, stresses relax only partially, leaving behind a finite persistent residual stress.

Residual Strain and Stress in Biocrystals [PDF]

Advanced Materials, 2018
AbstractThe development of residual strains within a material is a valuable engineering technique for increasing the material's strength and toughness. Residual strains occur naturally in some biominerals and are an important feature that is recently highlighted in biomineral studies.

Characterisation of residual stress state and distortion in welded plates stress engineered by local mechanical tensioning [PDF]

, 2014
Local mechanical tensioning is one of the most efficient and industrially relevant stress engineering techniques to modify weld residual stress field and subsequently reduce buckling distortion. However, application of rolling load and its magnitude need

Size effects on residual stress and fatigue crack growth in friction stir welded 2195-T8 aluminium - Part I: Experiments [PDF]

, 2011
Residual stress fields were measured in three different sizes of Compact-Tension (C(T)) and eccentrically loaded single edge notch (ESE(T)) specimens containing transverse or longitudinal welds. The effect of size on residual stress profiles was studied.

Problems in using a comb sample as a stress-free reference for the determination of welding residual stress by diffraction [PDF]

, 2010
Precise measurement of a stress-free reference lattice parameter is vital in the determination of residual stress by diffraction techniques using θ/2θ-based analyses.
