Rosette Data Reduction
A
calculator for
Principal Stresses & Strains
With strain measurements made with a rectangular rosette on homogeneous, linearly elastic, orthotropic materials.

Independent Variables
Modulus of Elasticity (psi, Pa, etc.),
Poisson's Ratio (nondimensional),
Measured Strains (microstrain),

= +45 degrees.
if
