| Abstract Scope |
It is obvious that the digital image correlation technique is a useful tool for measuring strains in tension or compression, but what happens if you want to measure very large deformations? How about when for correlation field breaks down, non-traditional sample geometeries, or non-uniform deformation?
Obviously, the strength of DIC is that it can be used to measure strain fields across an entire sample that can be observed during loading. It is good for any geometry and at any loading rate where images can be captured and can be used on 3-D samples. In this talk examples will be presented that show how the technique can be used to measure strains to 90%, how to use the technique to measure crack boundaries for crack velocity and fracture toughness, and for geometries where there is non-uniform deformation (like shear). It is also ideal for small scale – high speed applications. |
