Residual stress

1
Residual stress Suppose isotropic solid loaded
in uniaxial tension
2
Residual stress Suppose isotropic solid loaded
in uniaxial tension
Comments Can vary with crystallographic
direction E, ? Mat'l can be anisotropic But,
if no preferred orientation, usually doesn't
matter
Biaxial triaxial stress states

Residual stress Measurement procedure -
classical technique - sin2 ? Stress state
resolved differently along different directions
in sample, so peak shifts change w/ direction
