Figure Legend:
Composite hip implant instrumented with strain gages and fixed in a cement-filled steel chamber. A metal ball was inserted at the proximal tip of the hip implant to simulate the femoral head. Black arrows show the strain gage locations 1 to 4.

Figure Legend:
Experimental setup used for mechanical cyclic testing of the composite hip implant. Tests were done first with strain gages mounted on the surface of the hip implant and then repeated with strain gages removed while imaging the implant using the IR thermography camera.

Figure Legend:
Correlation graph of surfaces stresses from IR thermography vs strain gages. Excellent agreement yielded a Pearson correlation coefficient of R2 = 0.96 and a slope = 1.01 for the line of best fit. Perfect agreement would have give R2 = 1 and slope = 1. All stress values are combined on the graph, regardless of axial force level used or the tensile or compressive nature of the stress. All stresses are Von Mises.

Figure Legend:
IR thermography grayscale images of three-dimensional surface stresses on the composite hip implant for the three cyclic force levels of 840 N, 1500 N, and 2100 N. Stresses were extracted from locations 1 to 6 and the “max” point. Locations 1 to 4 corresponded to the strain gage sites. Stress scales given by the camera do not include the maximum or minimum stress values.
