Micro-Measurements - PhotoStress® Plus - Case Studies

Biomechanical Tests:

Among the more intriguing and significant applications for PhotoStress testing are those in the field of biomechanics. Areas of application, to name a few, include stress analysis of skeletal parts such as the femur, pelvis, and skull; knee, elbow, and other joint replacements; dental implants and bridges; and mechanical medical aids such as forceps and surgical staplers. PhotoStress analysis of the proximal femur was undertaken to evaluate the stress transfer for total hip replacement. Photo A shows the fringe pattern on the femur before the implant was inserted. Photo B shows the implant in place, and Photo C shows the change in strain distribution on the surface of the femur when compared to the photo before implant.
