Finite element analysis (FEA) involves breaking a model down into small pieces called finite elements. FEA was first developed in 1943 and involved numerical analysis techniques. By the 1970s, FEA was used primarily by aerospace, automotive, and defense industries due to the high cost of computers. Modern FEA involves preprocessing like meshing a model, applying properties and boundary conditions, solving the model using software, and postprocessing to analyze results like stresses and displacements.
Composite materials are increasingly being used in aircraft structures due to benefits like weight reduction, corrosion resistance, and tailorable properties. Regulations require material properties to account for manufacturing defects and the environment. The Boeing 787 uses composites for around 50% of its airframe structure. Composites are best suited to highly loaded parts where their high strength and stiffness provide critical weight savings.

Experimental Stress Analysis and Optimization of Connecting RodIRJET Journal
The document discusses experimental stress analysis and topology optimization of a connecting rod. It begins with modeling the existing connecting rod using CAD software and performing finite element analysis to determine stresses and deformation. Topology optimization is then used to remove material from low-stress regions to reduce weight without compromising strength. The optimized model is again analyzed using FEA. Finally, the optimization results are implemented on the physical connecting rod using EDM machining. Strain gauges are mounted and experimental testing is conducted to correlate results with the FEA analysis. The optimization reduced the connecting rod weight from 2.351kg to 2.240kg while von Mises stresses and deflections remained within acceptable limits.
