Residual Stress measurements can be measured using two zero degree shear horizontal waves in orthogonal orientation which provides a Birefringence (%age) parameter directly related to the stress. Emats can easily generate linearly polarized SH waves in Aluminum.

Innerspec Technologies Inc also represented in Chinal has a specific emat probe to measure residual stress using their portable Power Box-H instrument. Kindly consult Innerspec Technologies for more details.
