Methods of Obtaining Magnitude and Direction of Principal Stress (Rosette Analysis)
Generally, if the direction of principal stress is uncertain in structure stress measurement, a triaxial rosette gage is used and measured strain values are calculated in the following equation to find the direction of the principal stress. (The following equation is only for specified angle triaxial rosette gages.)
