High-resolution optical measurements of miniature metal samples for microstructural engineering applications with FlexDIC

The Department of Mechanical Engineering at the National University of Singapore (NUS), has acquired a FlexDIC system for high-resolution optical
measurements of miniature metal samples for microstructural engineering applications.

The FlexDIC is an ideal measurement technique for such application since it is very accurate (the strain resolution is as low as 10 μstrain), yet flexible that it can be used for an array of applications.

Assistant professor, Dr. Tan Xipeng, and his PhD student, Chen Mingzhang from the Mechanical Metallurgy Lab says “the FlexDIC solution is ideal for performing the microscopic tests that we require. In particular, it helps us to identify and quantify localized plastic deformation behavior of our 3D-printed heterogenous metal samples.”
