Comparisons of experimental and FE results show that validation metrics were insensitive to constitutive model. a Bland–Altman analysis of contact area. b Bland–Altman analysis of peak contact stress. c Bland–Altman analysis of average contact stress. Differences were calculated by subtracting the FE predicted value from the experimentally measured value. Differences greater than zero indicate larger experimental results than FE predictions. Error bars tolerance intervals corrected by the design effect
