Dynamical mechanical analysis
WebA: Dynamic Mechanical Analysis (DMA) is a dynamic characterization technique that measures stress as a function of strain, or force as a function of displacement. It involves applying a sinusoidal strain to the material and measuring the resulting stress. Typically, DMA also involves varying the frequency of the strain and/or the temperature of ...
