Appendix D. Tables and Charts

The properties of materials vary widely depending on numerous factors, including chemical composition, manufacturing processes, internal defects, temperature, and dimensions of test specimens. Hence, the approximate values presented in Table D.1 are not necessarily suitable for specific application. Tabulated data are for reference in solving problems in the text. For details, see, for example, Refs. D.1 and D.2.
