Experimental Verification of Stresses in a Spherical Element

Thin-walled structures that consist of rings, shells and plates are widely used as the elements of marine machinery. The analysis of stresses and strains of these elements is one of the most important bases of construction and plays the decisive step in their design. This work presents comparative stress analysis in a coupling unit activation element of marine auxiliary steering gear. Performed analytical solution is based on the moment theory of thin shells of revolution and theory of thin plates. Experimental solution was founded by using the 3D photoelastic frozen stress method on Araldite B model of element. On the basis of analytical and experimental solution, the curves of radial, meridional and circular stresses were comparatively drawn and analysed.
