Optical Strain Measurement Vs. Traditional Strain Gauging

Leave a Comment

In mechanical engineering, “strain” refers to the degree and the way a structure deforms under a load. An understanding of the strain behavior, combined with the knowledge of the failure mechanisms of structural materials, allows intricate yet robust designs of modern, high-performance aerospace machines, including rocket and jet engines. High-speed rotors, such as jet engine […]
