Sažetak
An approach to design elements with stress concentration made from laminated composite orthotropic materials has been proposed. Results of numerical and experimental analysis of the stress concentration factors, for two series of five models in the form of plane strips with elliptical holes, are presented. Models in cases of plane stress loaded uniaxial in tension/compression and in pure bending have been investigated. The strength values of orthotropic materials are depending on orientation to the principal material axes. Therefore the reduced stress concentration factors for all cases of the model loading are defined and calculated. In order to determine these specially the stress concentration factors and the ultimate loading capacity of the strips the Gol´denblat-Kopnov failure criterion for orthotropic materials were used. Values of the stress concentration factors and the reduced stress concentration factors for all applied loads of all examined models were obtained and in this paper graphically in diagrams are shown.
