Using MAPLE 10, a creep curve has been formulated, which represents the mechanical behavior of metals, polymers, and ceramics, for instance. Creep tests are carried out on specimens loaded, e.g., in tension or compression, usually at constant load, inside a furnace which is maintained at a constant temperature. The extension of the specimen is measured as a function of time. A typical creep curve for metals, polymers, and ceramics exists of three parts and is represented in this Maple worksheet.
