Utilizing an "Ashby chart" is a common method for choosing the appropriate material. First, three different sets of variables are identified: • Material variables are the inherent properties of a material such as density, modulus, yield stress, and many others. • Free variables are quantities that can change during the loading cycle, for example, applied force. WebThe performance equation contains groups of material properties. These groups are the material indices. Sometimes the ‘group’ is a single property; thus if the performance of a beam is measured by its stiffness, the performance equation contains only one property, the elastic modulus E. It is the material index for this problem.
