Systems and methods for measuring material degradation

DWPI Title: Detecting strained state of engineered material for measuring material degradation and used as indication of change of property of material upon release of tracer gas from material, involves applying stress to engineered material to release tracer gas from engineered material
Abstract: Systems and methods that measure material deformation by measuring a tracer gas that has been added to or is present in an engineered material that is subsequently released from the material, measured, and correlated to a change in a property of the material upon a stress/strain being applied to the engineered material.
Use: Method for detecting strained state of engineered material, for measuring material degradation and used as indication of change of property of material upon release of tracer gas from material.
Advantage: The method passively and accurately measures material degradation under a wide range of circumstances.
Novelty: Detecting a strained state of an engineered material, involves homogeneously fixing within the engineered material an amount of a tracer gas when forming the engineered material; applying a stress to the engineered material to release the tracer gas from the engineered material; and sensing an amount of tracer gas released from within the engineered material and associating the amount of tracer gas sensed to the strained state within the engineered material; where the engineered material is glass, ceramics and cermets.
