Test artifact for non-destructive evaluation
| DWPI Title: Test artifact used for non-destructive evaluation includes first cantilever section disposed on support frame, and section comprises cantilevers, second cantilever section, support beam, end portion, protrusion and mounting portion |
| Abstract: The present invention relates to an additively manufactured (AM), monolithic, multi-axis linear flexural cantilever test artifact. The artifact is monolithic in that is it one continuous part with no assembly. The artifact can be non-destructively evaluated and includes a support frame, cantilevers, and a mount. |
| Use: The test artifact is useful for non-destructive modal analysis comprising imparting an impulse to the cantilevers of the test artifact, preferably one axis at a time, and using sensors to measure time-dependent evolution of position and in an automated test sequence and be done with quick turn-around. |
| Advantage: The test artifacts enables repeat evaluation of the same part in varying environments to determine changes in the material properties and mechanical response, preferably after repeated heat treatments or surface modifications, utilizes the flexural cantilever that simultaneously enables non-destructive determination of bulk transport properties for metals of electrical resistivity, and indirectly, via calculation, also the thermal conductivity and can also be modified and/or tailored for specific needs. |
| Novelty: Test artifact (100) comprises: a support frame (102); a first cantilever section (104) disposed on the support frame, where the first cantilever section comprises first cantilever and a second cantilever; a second cantilever section disposed on the support frame and substantially parallel to the first cantilever section, where the second cantilever section comprises third cantilever and a fourth cantilever; a support beam connecting the first cantilever section to the second cantilever section; an end portion connecting the second cantilever to the third cantilever and disposed on ends of the second and third cantilevers opposite the support beam; a protrusion disposed on the end portion; and a mounting portion attached to the support frame. |
