Abstract The present paper describes the numerical and experimental methodology for the analysis of stress and deformation state in structural elements with geometrical discontinuities. Research is based on structural elements of the connection lug type and stress and deformation state. Numerical analysis is conducted by applying the finite element method (FEM) in a KOMIPS® and ABAQUS® software package. Experiments are performed at the Laboratory for Stress and Deformation Measurements, Faculty of Mechanical Engineering, Belgrade, using GOM equipment and ARAMIS® software application. The paper demonstrates how it is possible to anticipate the results by applying FEM. A short review of current research in the field of structural elements with geometrical discontinuities is given within the framework of the paper. Keywords: connection lug, finite element method (FEM), experiment, stress-strain distribution |
