Rubber Performance Validation Through Crack Growth Testing

Presented by Adam Harris and Travis Parkman



Crack propagation in rubber is fundamental for many important applications and more than we might realize. For instance, consider the vehicle you take to work every morning. To arrive at your destination safely, you rely on numerous rubber components, such as belts, seals, hoses, and tires, to function properly at their designed strengths. However, as materials age and are repeatedly deformed by cyclic loads, small cracks will initiate and propagate over time; eventually leading to premature failure. Depending on the component, failure can mean a small annoyance such as replacing worn windshield wipers to devastating consequences, such as unneeded loss of life due to a tire blowout.

Accurately quantifying the crack growth behavior of different rubber compounds has become a priority in research and industry. This webinar will discuss some of the factors that affect crack growth by reviewing previous works in this field. This includes the addition of alternative fillers, mixing procedures, and ageing. Case studies using Metravib DMA+ series and crack growth module will also be highlighted. This webinar is recommended for any researchers, engineers or associates involved in the rubber industry.
