VisEng's thermoelastic analysis determines the surface stress distribution in dynamically loaded structures and is particularly good for determining potential failure sites. The technique uses an extremely sensitive infra-red array camera which is capable of measuring minute temperature changes induced in the component during dynamic loading. The applications range from automotive, aerospace, composites, structures, contact stresses and other industrial applications.
Automotive
Connecting Rod
Wheels
Composites
Damage Evolution 17MPa
Damage Evolution 86MPa
Measurement of damage evolution in advanced composites, stress concentration factors, and plastic zones. These damage evolution images were performed on a 0/90 weave alumina/alumina double notch ceramic matrix composite.
Structures
Stresses in structural metal plate connectors
Industrial
Notch
Crack
Hook and Clevis chain link
Aerospace
Non Destructive Evaluation. Picture shows stresses in a door latch assembly experiencing dynamic loading.
Contact Stresses
Contact Stress Distribution Measurement. Picture shows a plastic sample which is in contact with a flat barium fluoride window.
Thermoelastic analysis is an essential technique to improve your design, prototyping and testing of a wide variety of components. It is the perfect partner to many important new technologies, including:
• Rapid Prototyping (evaluation of components produced by Rapid Prototyping)
• Finite Element Analysis (full-field verification of the accuracy of finite element models)
• Non Destructive Evaluation (used for thermal NDE)
