Selección de materiales en el diseño mecánico: estudio de una metodología para la selección de materiales en el diseño mecánico.

Abstract

The present document studies in a detailed way the theoretical-methodological strategy developed by Dr. Michael Ashby for the Selection of Materials with a direct application in Mechanical Design. Seeking to constitute a guide of use for this method in order to support the design branch of Mechanical Engineering to achieve better performance results in later stages of manufacture. The digital tool developed by the Department of Engineering of the University of Cambridge with the leadership of Dr. Ashby CES Edupack is used in this work, taking as reference the Level 2, 3 and Ecodesign databases where the entire universe of materials that are included is implemented in the analysis: metals, ceramics, polymers, fibers, composites, and natural materials. For a more direct approach within the Design of Mechanical Elements, the mechanical, physical and thermal properties of the materials that are closely related to the key performance indicators of material or shape are considered for case study analysis. Through the use of these KPI’s, two properties of the materials are compared in such a way that bar or bubbles graphs called Ashby Diagrams are obtained through which compliance with the design requirements for each case can be verified, thus corroborating the existence of the relationship between the functional part of a mechanical element, the materials from which it is made, the shape that has been given to it in its design and its manufacturing process.
