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.

ALTAIR LI allows testing of structural components undertaking random, transient or dynamic loading.In some applications where there can be large displacement, a software feature is available to provide accurate motion compensation.

ALTAIR LI uses a JADE or SILVER camera which provides thermal images of the scene at fast frame rate The transformation of these thermal Images into stress lmages is made by software, without any contact with the material surface.
