Datasheet: Infrared Imaging Software: Altair LI

ALTAIR LI provides full field stress images in real time by using the thermoelastic effect which states there is a linear relationship between the temperature changes induced by loading and the stress at the material surface. The required thermal resolution to achieve a resolution of 1 MPa depends on the material properties, it is typically equal to 1 mK for steel and 2 mK for aluminium.
