long term Polymer Durability Testing

Polymer materials are viscoelastic in nature. Their properties are highly time, temperature and stress dependant. The significance of this is often overlooked at the design stage. As a simple demonstration of the significance of this, the long term fatigue strength of polycarbonate is only 14% of the short term tensile strength quoted on manufacturers data sheets. For any engineering component subjected either long term static or dynamic loads or elevated temperatures a thorough understanding of the long term properties of the material is central to guaranteeing the durability of the final product.
