Principal Stresses & StrainsWith strain measurements made with a delta rosette on homogeneous, linearly elastic, orthotropic materials.
Modulus of Elasticity (psi, Pa, etc.),
Poisson's Ratio (nondimensional),
Measured Strains (microstrain), , ,
Principal Stresses (psi, Pa, etc.),
Direction * (degrees),
* Direction from Grid 1 to the maximum principal stress axis:
if = and < , then = = -45 degrees.
if = and > , then = = +45 degrees.
if = = , then is indeterminate (equal biaxial strain).
