dynamic mechanical analysis (DMA)

Dynamic Mechanical Analysis (DMA) is a technique used to measure how a material responds to stress or strain when subjected to oscillating forces, typically over a range of temperatures or frequencies. It helps determine properties like stiffness, elasticity, and damping, revealing how materials behave under dynamic conditions. DMA is valuable for understanding the mechanical performance of polymers, composites, and other materials, especially their flexibility and how they transition between rigid and soft states. This information guides material selection and design for applications requiring specific mechanical performance under dynamic or fluctuating forces.
