A novel procedure for selection of materials in concept design
Date of Original Version
This work is concerned with the selection of materials for conceptual product design prior to precise definition of part geometries. The proposed selection method is based on normalized scales of 0 to 100 for all fundamental material properties. The proposed scales are independent of the units which are used for the material property values. Three important transformations of the scales are demonstrated. First, the inverse material property is simply represented by 100 minus the original scale value. For example, if a material scores 83 for weight, then its scale value for lightness is 17. Second, a procedure is given for transformation the "100-scales" of individual properties to the "100-scale" of any derived parameter. Finally, a general procedure is established for the selection of multiple parameters with weighting values if desired. A spreadsheet sample database is presented suitable for teaching or demonstration purposes.
