Summary:Shear stresses arising between the surface and a studded outsole during running were identified by the use of photoelasticity. A bespoke experimental set-up was designed to capture the dynamic maximum shear stress fringes occurring when a studded outsole came into contact with the photoelastic surface. Image processing methods were used to clearly identify the fringes. Examples of analysis techniques were outlined; focussing on the use of the greyscale intensity of the photoelastic fringes to calculate the subsequent shear stresses.
