Analytical Strain Gauge

What is Analytical Strain Guage?

The stress analysis with strain gauge is used to determine the stress in a single component. In the stress analysis with strain gauges, usually bridge circuits are used with only one active measurement grid.

However, when it comes to a uniaxial stress condition, it is sufficient to detect the strain with a single measuring grid. The direction of the mechanical stress is required in this case, as known. The strain gauge is used to determine the amount of strain.

To calculate the mechanical stress from the measured elongation, it is essential to know

• The modulus of elasticity of the material as well as
• The k-factor of the strain gauge

If it is a two-axis voltage state, the main voltages and the direction of the main voltages should be determined. Three determination equations are required to determine the three unknown quantities. Therefore, three measuring grids are used in three linearly independent directions, e.g. 0°, 45°, and 90° or 0°, 60° and 120°.

For this task, there are strain gauge rosettes with three active measuring grids. For the calculation of the mechanical stress from the measured strain, the modulus of elasticity of the material, the cross-contraction number of the material, and the k-factor of the strain gauge must be known.
