Dynamic modulus

Dynamic modulus, often referred to in the context of materials science and engineering, is a measure of a material's stiffness or resistance to deformation under an applied load or stress, typically as a function of frequency. It is particularly relevant in the fields of pavement engineering, materials characterization, and the study of viscoelastic materials. In pavement engineering, for instance, dynamic modulus is used to characterize hot-mix asphalt (HMA) and can be an important parameter in mechanistic-empirical pavement design.
