Objective: To compare the deformation and maximum stress developed on a structural steel model for the given two cases, to select valid design as per analysis standpoint. Software Used: Ansys-19.0-Workbench. Material: Stainless steel. Given cases: Case-1: Case-2: Process flow in FEA: Procedure: Open Ansys Workbench.…

Objective: To read the data from the file provided and perform some calculations and also to plot the graphs between different parameter.   Concept: The concept is to read the data file(engine_data.out) provided. Actually, the data file name with extension is taken from the user and then the data file is read. Then…

Curve fitting: Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in…

Aim: To create B-Pillar Trim, Dog House, Locators and Ribs from a B-Pillar’s A-class surface and Master sections by following OEM Standard Design Rules. Software Used: CATIA-V5,KEYSHOT-9.
