DMA measures stiffness and damping, these are reported as modulus and tan delta. Because of a sinusoidal force, the modulus can be expressed as an in
During DMA testing, we apply oscillating strain and measure the resulting force while changing the temperature. This process allows us to determine the
The relative ratio of the loss modulus to the elastic, or storage, modulus is called tan (δ) and represents the relative amount of energy being dissipated versus elastically stored in a material.
