Modelling and Stress Analysis of Aerospace Bracket Using Abaqus

In aerospace applications, every aspect of aircrafts is fixed by using tens of thousands of brackets to assemble the parts. Design of brackets in aerospace engines is a crucial part which needs to have inspection of numerous shapes and sizes. Main applications of these brackets are mounting bleed air ducting, starter air duct fuel lines, and hydraulic lines’ engine core. These brackets are continuously subjected to constant and cyclic loading, which generates high amount of stress. So, the inspection is done manually which is time-taking and error-prone. To improve examination capability, many researchers have attempted to develop inspection techniques using certain software’s. Abaqus is one of the software’s, used for finite-element analysis and computer-aided engineering in the automotive, aerospace, and industrial products. This software is used in research institutions in engineering because of the wide material modelling capability and the editing capability. In Abaqus, the users can construe their own materials; as a result, new materials could also be simulated. Abaqus also facilitates compilation of multiphysics capabilities like coupled acoustic-structural and structural-pore capabilities. So, it is convenient for production-level simulations. In this paper, a 3D prototype of the bracket used in aircraft engine component is created and the von Mises stress analysis is done. As this bracket undergoes continuous load, more stress is developed in it which may lead to failure of the material. Hence, the deformation and failure are examined using this Abaqus software (early monitoring is possible). A 3D vision monitoring is also done by using finite element analysis. The result is assuring for large-scale industrial application.
