An Exploration of Several Structural Measurement Techniques for Usage With Functionally Graded Materials

<p>Titanium / titanium boride functionally graded 6x1x1 beams were subjected to a four-point beam test in order to critique the value of several measurement techniques. Also finite element analysis results were compared with experimental values and general observations about the experiment were recorded. Uniform 85% TiB / 15% Ti and uniform commercially pure titanium specimens were also subjected to the same loading conditions as a control. Techniques used include digital image correlation fiber optic strain gauging strain gauging and differential infrared thermography techniques. The strain data results were compared with one another and to linear finite element models. It was found that several of the techniques had distinct advantages and disadvantages for usage in a layered functionally graded system. Furthermore the finite element showed good agreement with results when overlaid with several of the measurement techniques.</p><p>This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it.
