Applications of FEA in Mechanical Engineering Dissertation Research

FEA can be applied to various fields within mechanical engineering, including:

1. Structural Analysis
   FEA is widely used to analyze structures and components under various loading conditions, such as pressure, temperature, and mechanical forces. It helps engineers understand how materials will deform or fail under stress and optimize designs for safety and efficiency.

   Example Research Question: How does the stress distribution in an aircraft wing under varying load conditions affect its structural integrity?

2. Thermal Analysis
   Heat transfer analysis is another common application of FEA. Engineers use FEA to model the distribution of temperature across a material or system and predict how heat flows through solid bodies or fluids.

   Example Research Question: What is the impact of thermal cycling on the performance of heat exchangers in power plants?

3. Vibration Analysis
   FEA is often used to analyze vibrations in mechanical systems, such as turbines, engines, and bridges. It helps predict resonant frequencies and modes of vibration, which are crucial for designing systems that avoid catastrophic failure.

   Example Research Question: How can FEA be used to predict the resonance frequencies of a rotating shaft in an industrial pump?

4. Fatigue and Failure Analysis
   FEA helps assess the durability of materials and structures over time by simulating fatigue conditions. This is particularly important in industries like automotive or aerospace, where components experience repetitive loading and need to be designed for longevity.

   Example Research Question: What is the effect of cyclic loading on the fatigue life of titanium alloys used in jet engine components?
