Strain measurement | Dewesoft

Strain rosette. A single strain gage can only measure in one direction. To overcome this, we use a strain gage rosette. It is an arrangement of two or more closely positioned gage grids, separately oriented to measure the normal strains along with different directions in the underlying surface of the test part. Rosettes are designed to perform ...
