Validation of vibration analysis using photo-elastic coatings

Abstract

The analysis of vibrations is performed using a plate bending element assuming that a coating has no effect to the motion of the plate. The stresses in the coating are calculated by using the procedure of conjugate approximation. Then the relative error norms for the finite elements are determined. They are represented graphically and serve for validation of the results of calculation in hybrid experimental-numerical proceduresprocedures.
