PHOTOELASTICIMETRY APPLICATIONS IN BIOMECHANICS

Abstract

The connecting elements of strength, in terms of mechanical resistance, included in the skeleton, that are loaded with  exterior forces are being deformed and, as a consequence, inside those elements is implied a state of stresses, witch is determined by the forces that hold together the particles of a solid. The study is conducted on a plane model made of epoxy resin, that represents a longitudinal strip of the upper extremity if the human hip. The study of the light fringes distribution that occur after the application of compressive and bending loads in a vertical plane was made using the photoelasticimetry method for the experimental analysis and the finite element method for the numerical analysis.
