Disk bending shear testing and system

Abstract:

A method for determining a shear property of a sample includes supporting a sample at three or more separate support locations about a periphery of a first surface of the sample in a testing fixture, the sample including a second surface separated from the first surface by a thickness, wherein the sample is axisymmetric about an axis that is orthogonal to the first surface. The method includes applying a load on the second surface of the sample with a load applicator in a direction substantially parallel with the axis, measuring, with a controller, shear testing data of the sample in response to applying the load, and determining, with the controller, a shear property of the sample from the measured shear testing data.
