This course is the second of ten (10) courses in a machine design course series. Each course in the series is stand-alone and can be completed without having completed the preceding courses in the series.
The objective of this course is to enable practicing engineers to gain a clear understanding of the stresses imposed on any industrial machine or its elements.
Any machine consists of components that work in unison to transmit loads on the structure and create the ability to function properly. The components could be in series or in parallel to perform the required functions. Loads on the structure could be static or dynamic or random by nature.
For example, loads on a machine could be cutting loads due to metal removal, gravity load due to its weights, thermal loads due to temperature, dynamic loading due to centrifugal actions, etc. The components of any structure need to be strong enough to carry the external and internal forces, moments, and torque without premature failure.
Machine design consists of identifying functional requirements, selection of mechanisms and structure, concept development, design stress, strength, and life analysis, and verifying the design analytically to satisfy the cost, manufacturing, and functional requirements. Out of all these steps, the analysis step is very crucial for a successful and viable design.
The design analysis consists of various steps such as assumptions, determination of loads and forces (external and internal) for the machine under consideration, material selection to satisfy loads and forces, stress, strain, strength, and life calculations, and modifications or revisions, if necessary.
The focus of this course will be on stress, strain, and failure considerations for machine elements.
