Rosette Data Reduction

A calculator for

Principal Strains

With strain measurements made with a delta rosette on a homogeneous material.

Independent Variables
Measured Strains (microstrain), , ,

Dependent Variable
Principal Strains (microstrain),  
Direction^* (degrees),

Note
^* Direction from Grid 1 to the maximum principal strain axis:
if = and < , then == -45 degrees.
if = and > , then == +45 degrees.
if ==, then is indeterminate (equal biaxial strain).
