Research of rubber-metal hinge using brittle strain-sensitive coatings

The use of rosin strain-sensitive coatings for studying the deformation fields of parts located in different working environments, including oil vapors at 100 % humidity and temperatures of 5÷35 °C, is considered. Using the example of a rubber-metal hinge, the effectiveness of the proposed method for determination of the fields of principal stresses and assessment of the state of operability of this unit under loading with internal pressure and lateral force is shown.
