An application to calculate the factors which are used to determine the tensile rupture load of a lug under axial, transverse or oblique loading
Journal Title: INCAS BULLETIN - Year 2013, Vol 5, Issue 1
Abstract
This work describes a computer application to calculate the values of the factors which are used to determine the tensile rupture load of a lug under axial, transverse or oblique loading. It can be used as a procedure for identifying potential failure modes. Lugs are connector-type elements widely used as structural supports for pin connections in aerospace industry. Failure modes in lugs are functions of lug geometry and material mechanical properties. For a lug under axial load three modes of lug failure are considered: tension, shear and bearing. Under transverse load the load to cause rupture or unacceptable permanent deformation of the lug is given. Tension mode failure usually occurs in materials of low ductility. In materials with high ductility, the failure mode of a lug can be either tensile or shear tear-out, depending on the lug geometry. The application has a graphical interface that allows the user to use them with much ease and view immediately the results and provides a flexible ad-hoc print reports and diagrams that allow to present analysis information. It includes Microsoft Excel Object Library as reference to the Excel material properties file.
