Stress-Check System Image

MoviTHERM Stress-Check uses infrared non-destructive testing (irNDT) Thermoelastic Stress Analysis (TSA) to visualize stress measurement on metals, composites, plastics, glass, bone, concrete, and other materials. Stress-Check leverages the relationship between temperature and mechanical behavior laws with Lock-in Thermography (LiT) to measure the linear thermoelastic effect of a material under periodic, random, or cyclic loading condition. The system works with cooled and uncooled IR cameras with multiple lens configurations to meet various application requirements.

Stress-Check Benefits

VISUALIZATION OF STRESS PATTERNS

TSA rapidly “sees” stress characteristics in metallic, ceramic, composite, and other materials.

STRESS MEASUREMENT MADE EASY

Complex analysis technology simplified for stress measurement.

IR THERMOGRAPHY ADVANTAGES

Has many positive aspects of IR measurement.

How does Stress-Check work?

Applying a cyclic compression load on a solid material will cause it to experience small and reversable temperature variations. Synchronizing an infrared camera to the load cycle allows using Lock-in techniques to capture surface temperatures and then convert temperature measurements to stress units on a pixel-by-pixel basis.

Resulting image output displays a stress distribution map and software allows for the extraction of spot stress measurement from any image pixel.
