PRISM - Hole-drilling method an ESPI

PRISM is a new way to measure residual stress in a wide range of materials.

The system combines the hole-drilling method with digital imaging and ESPI (electronic speckle pattern interferometry). PRISM has advantages for stress depth profile applications with large number of similar samples.

Furthermore measurements can be done on materials, that are difficult to measure for XRD like titanium, plastics and copper.

Key Benefits

• Only direct visual path to part, no strain gages are required
• Fast measurement, complete stress depth profile starting from 10 min
• Output delivers the complete planar stress state
• Easy to use, software is based on Microsoft Windows
• Developement for unique applications
