Abstract
A load bearing member, such as a polymer cord reinforced belt, includes at least one element of a different material having a characteristic that distinguishes it from the polymer fibers that make up the strands of the cord. The element of second material has a configuration that is repeated along the length of the load bearing member. The configuration of the second material element provides a readily detectible indication of localized strain on the load bearing member. As the load bearing member is strained over time, the configuration of the second material element is also altered. Analyzing the configuration of the second material element along the length of the load bearing member provides information regarding the condition of the belt.
