Abstract

For the design engineer, the material selection stage is crucial by the selected material must fulfill the properties specified in the design and other requirements such as economic, weight, and manufacturing constraints. For this reason, the use of robust materials selection methodologies becomes essential. This article compared 14 materials selection, taking into account seven criteria: the Ashby, characteristic magnitudes, and the database methods obtained the highest score. These three methods were applied to materials selection for a Skateboard table. The design properties Skateboard table were defined based on a bibliographic review. ANSYS Granta selector Software was used to determine some material properties and calculate commercial laminated materials’ properties in cases that do not have references. The Ashby methodology selected Stiffness-limited design at a minimum mass material index. Mass, thickness, and cost characteristic magnitudes were calculated by the method of characteristic magnitudes. The MatWeb online database was used to apply the selection by database method. The best material selected by the Ashby methodology from 4169 was longitudinal Bamboo. The characteristic magnitudes method selected a laminated material consisting of 5 maple sheets and 2 outer bamboo sheets from 5 materials. Database method did not obtain any material, but it resulted in a list of 90 possible materials starting from 155,000. Ashby’s method was the best one for this application since all design properties could be included.
