Analysis on a plate with a hole

Aim: To write a code in Matlab to parse the NASA thermodynamic data file and then calculate thermodynamic properties of various gas species. Theory: NASA came up with polynomials that can be used to evaluate thermodynamic properties such as Cp, H and S. They have also documented the coefficients that are required to evaluate…

Aim:  To create a  model of a rotating flywheel on a shaft and identify 5 critical frequencies by generating 5 mode shapes. Boundary Conditions: Material Used = Alloy Steel Fixtures = bearing supports on either side of the shaft at stepped part of the shaft A Shaft with rotating flywheel is model using solidworks…

Aim: To perform static analysis on the plates with holes of different geometries and compare the results of stress , strain and displacement. Geometric Model of the plates: Case 1: Dimensions of the Plate : Length=300mmHeight=120mmThickness=30mmCircular Hole at the center:Diameter=60mm 3D Model of the Plate: Case 2: Dimensions…

Aim :- To perform a buckling analysis on a cyclonic separator stand.   To create a stiffener to the legs of the stand and determine the increase in buckling factor of safety. To perform parametric design study to run simulations at different positions of the stiffener and obtain the optimum position for the stiffener…

Aim: To compare the bending performance and suggest best out of the following three beams. Case 1 : Case 2: Case 3: Introduction: A beam is a structural element that primarily resists loads applied laterally to the beam's axis. Its mode of deflection is primarily by bending. The loads applied to the beam result in reaction…
