Stress Image: Stress image showing fatigue crack
Visual-Stress Fusion: Visual-Stress overlay identifying precise location of fatigue crack
A World First
The LTS-640V boasts the fidelity of a high-end R&D instrument with the ruggedness, versatility and ease-of-use of an industrial tool.
Applications include:
- Validation of structural FEA (Finite Element Analysis)
- Identification of areas of structural weakness
- Structural health monitoring
- Detection, monitoring and characterisation of fatigue cracks
- Non-Destructive Inspection (NDI)
- Research and teaching in structural mechanics
Advanced Stress Imaging, Simplified
With an ultimate stress sensitivity of < 1 MPa1, the 1MILLIKELVIN LTS-640V has ample precision for the most demanding of applications, but none of the complexity you might expect. Getting started is a matter of ‘plug and play’.
The in-built visual sensor along with the visual-stress fusion function allows for easy identification and location of critical stress regions.
MiTE Suite
