An Evaluation Study on Fatigue Life of U-shape Aluminium and Structural Steel Fatigue Sensor
Tariq Salem Alshahbouni, Dr. Ali Gungor
Abstract: Fatigue is the most widely recognized reason for failure in metal structures. Fatigue is not a new phenomenon, it has confounded researcher for more than 200 years. The issue with fatigue makes attention with the applications of metal in various structures. In recent years, impressive efforts have been made for the development of analytical and additionally numerical models for the better estimation of fatigue life for critical component structures. Developing a fatigue damage detection sensor to monitor the structural damage accumulation of critical mechanical or structural components working under cyclic loads before any fatigue failure occurs. The practice of designing structures to take into account fatigue is highly abstruse since the actual loading history of the structure is not known and cannot be accurately predicted. In this way, there is a requirement for a device which would monitor fatigue damage and provide a reliable estimate of remaining fatigue life of a specific structure altogether to provide a warning of impending fatigue failure, it is called fatigue sensor. The main objective of this study is to analyze and an evaluation study on fatigue life of U-shape Aluminum alloy and Structural steel fatigue sensor. As simulation tool for the purpose of this paper, the finite element software is ANSYS Workbench. Based on numerical results, the maximum fatigue life was at U-shape radius (r = 20 mm) Aluminum alloy and Structural steel, the minimum fatigue life was at U-shape radius (r = 5 mm) Aluminum alloy and Structural steel.
