Some products are expected to be completely rebuilt or replaced after 10 years; others may be replaced after less than one year. The safety factor is therefore determined by the norms (specifications) of the industry. For a new product in a new industry with no established product life expectancies, testing the product and measuring the stress level for failure can determine a safety factor. These values, measured against original material properties, will provide a good starting point for establishing time-related safety factors.
Plasticity occurs when the stress goes beyond the yield point on the stress-strain curve for any given material. This material property can be utilized in cold-forming processes for some plastics. Increases in temperature greatly affect plasticity, especially in thermoplastic resins. 4 Ductility The material’s ability to be stretched, pulled, or rolled into shape without destroying its integrity is called ductility (Fig. 16). Polymers are categorized as ductile or brittle at a given temperature.
9 Creep Plastic parts exhibit two important properties that can occur over long-term loading: creep and stress relaxation. 1 Introduction When a constant load is applied to a plastic part, it induces an internal stress. Over time, the plastic will slowly deform to redistribute the internal energy within the part. A test that measures this change is performed by applying a constant stress over time. This time-related flow is called creep. 33 shows a creep experiment in which a specimen bar is held vertically from one end.
