Home - Stress Analysis Strain Gages - Calculators - Three-Element Rectangular (45 deg) Rosettes (calculator): Transverse Sensitivity

Transverse Sensitivity Errors

A calculator for
Three-Element Rectangular (45-degree) Rosettes
With a separate transverse sensitivity for each grid.

Independent Variables
Indicated Strains (microstrain),
Transverse Sensitivity* (%),
Poisson's Ratio** (nondimensional),

Dependent Variable
Actual Strains (microstrain),

* Grids 1 and 3 of planar rosettes commonly have the same transverse sensitivity.
** The Poisson's ratio of the material on which the manufacturer's gage factor was measured (usually 0.285).
