Dynamic Mechanical Analysis (DMA) is crucial for characterizing rubber's viscoelastic behavior. Recent Alpha Technologies DMA advancements include fatigue testing and HeatBuildUp (HBU), based on ASTM D623, which measure internal and surface temperature during significant sinusoidal displacement. This is vital for the tire industry to predict overheating and compare rubber formulations' self-heating susceptibility. Combining HBU and DMA offers precise control over force/displacement and simultaneous monitoring of viscoelastic properties (complex modulus and Tan delta) alongside temperature. This presentation detail the methodology, explore the influence of parameters like frequency and strain on self-heating, and demonstrate the method's practical utility for the tire industry.
