The experimental-calculated method for determination of contact stresses is reported. The method is based on hybrid use of photoelasticity and finite element method (FEM). The results of contact pressure and contact angle determination in hinge joint as function of value and direction of load, clearance are presented. The contact stress distribution in three-dimensional hinge joint is shown which depend on elastic deformations of pin and lug.
