Resilience testing of a rubber or plastic compound is a measurement of how elastic it is when exposed to various stresses. Measurement of a material’s resilience can assist engineers and scientists with choosing the right material for a given application.
Another common method is dynamic mechanical analysis (DMA), where stresses are applied to a given material and the strain in the sample is measured. Temperature and frequency of the stress are additional variables that are commonly used to measure characteristics such as:
What is Resilience Testing?
Resilience is the ratio of energy released in deformation recovery to the energy that caused the deformation. One test method is the Bayshore Resilience method. It calls for the dropping of a weighted ball from a specified height onto a given material sample. The rebound height of the ball is then measured and used to determine how resilient the material is to the stress. The result is an indicator of hysteretic energy loss. The percent rebound measured in the test is inversely proportional to hysteretic loss.Another common method is dynamic mechanical analysis (DMA), where stresses are applied to a given material and the strain in the sample is measured. Temperature and frequency of the stress are additional variables that are commonly used to measure characteristics such as:
