Measurement of crack growth using DIC on a CT sample

Q400 DIC system measures the crack propagation at a CT specimen under tensile load.

The video shows the measured major strain together with the recorded force.The diagram gives the crack length versus force. The yellow vectors mark the rapid crack propagation with force reduction.

This application example shows the possibility of detecting cracks, locating crack tips and measuring crack opening and crack growth using the Q400 DIC.
