MATERIAL TESTING application example

Measuring the strain distribution during a tensile test on a CFRP sample

The strain distribution on a CFRP specimen with hole is measured optically with a Q400 DIC ystem.

The right image shows the strain after the initial failure state of the specimen.

This application example shows the use of the Q400 digital image correlation system at CFRP composite materials. The measured strain field shows invisible microcracks before the component fails.
