Design Course for Mechanical Engineer
Take your mechanical engineering skills to the next level with a comprehensive design course built specifically for engineers. From stress analysis and CAD modelling to materials selection and topology optimisation, every module connects theory directly to practical design decisions. This course gives you the tools to design components and systems that are safe, manufacturable, and optimised for performance.
What you will learn:
You will master the full engineering design process, from defining requirements and generating concepts to validating final designs using FEA and robust design methods. You will develop hands-on proficiency in parametric CAD modelling, GD&T, and technical drawing standards used in industry. The course covers mechanical component design for shafts, gears, bearings, springs, and fasteners, with rigorous stress and fatigue analysis methods throughout. You will apply systematic materials selection using Ashby charts and learn design for manufacturing rules for machining, casting, sheet metal, and additive manufacturing. Advanced topics include topology optimisation, Taguchi methods, failure analysis, and lifecycle-aware design strategies.
