The present study revivals the analysis of crack on aeroplane wing at different positions. Also states the deformation of wing structure against the different positions of crack on aeroplane wing. For this study the NACA 4412 Clark-y profile is used to generate aerofoil shape of aeroplane A320. Again the model is generated in CATIA v5 R21 software for further analysis. The ANSYS is used to carry out harmonic response analysis for prediction of deformation against pre loading condition at different positions of crack on wing. This shows the variation in results for different positions of cracks on wing to decide the maximum deformation of wing structure.

–In this research manufacturing of the Kevlar-Mg AZ31B sandwich composite is done. Sandwich is prepared using Kevlar fiber and Mg AZ31B alloy. This sandwich composite is manufactured by Vacuum Assisted Resin Transfer Moulding (VARTM) method. This method uses the vacuum and pressure difference causes the bonding of fiber- metal surface using epoxy resin. In this sandwich composite Mg AZ31B alloy act as core material and Kevlar fiber as a face skin. This fiber-metal sandwich composite will have enhanced mechanical properties than core material. Key Words:Kevlar, Mg AZ31B alloy, Sandwich composite, VARTM.

Now a days the IC Engines are widely used. Connecting rod is used to connect the piston to the crankshaft. As it plays very important role its analysis should be carried out. In this presented work connecting rod of two-wheeler is modeled using CATIA v5 R21 software. After modeling of connecting rod it is made available for analysis in ANSYS. In the ANSYS Workbench static analysis of connecting rod is performed. Analysis is performed for different materials like Cast iron, Copper alloy, Silicon anisotropic, Structural steel and Titanium alloy to find Von misses stress coming on the connecting rod. From above analysis it is shown that Titanium alloy is most suitable material for the two wheeler connecting rod.
