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

The study focuses on the performance of functionally graded titanium and titanium boride beams under a four-point beam test, assessing various measurement techniques. It compares experimental data with finite element analysis, highlighting the effectiveness of methods such as digital image correlation and fiber optic strain gauging. The research reveals distinct advantages and disadvantages of these techniques in layered systems, while also demonstrating that finite element models align well with the experimental results, providing valuable insights into the behavior of these materials under stress.
