Comparative Study of Stress and Strain of Orthopaedic Implants for the Hip with Photoelastic and Image Correlation Techniques

The present study comprises a comparative exercise to determine stress, strain, and amorphic structural state in a hip prosthesis with the use of the photoelastic and image correlation technique. Several photoelastic models, some of them with a stochastic finish were created by the use of a computed tomography scan, stereolithographic three-dimensional printing, and rapid prototyping. Ideally, our results could yield a significant time reduction of techniques aimed to evaluate stress and strain of surgical models either pre or postoperatively.
