Measuring 3D Volume of Rubber Torus
In this test, a rubber puck is mounted between two grips, and a set of reference images are acquired from a CT scanner at know increments. Each ‘slice’ of data is then analyzed to compute a static volume measurement. After the puck undergoes a compression load, images are acquired again by the CT scanner at the same locations. Digital image correlation algorithms are used to calculate the volumetric change or deformation at each individual voxel, which make up the 3D volume.
The animation below displays the internal strain (Ezz) of a rubber puck undergoing compression. The volumetric strain data can be viewed, analyzed, or extracted as a volume or as individual data slices. The internal compressive strain can clearly be seen. This test is a useful demonstration of the power of the VIC-Volume System.
