Dashpot viscosity
WebYou'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: The behavior of a polymer is described by a Maxwell model consisting of a spring element of modulus 1010 Pa and a dashpot of viscosity 1012 Pa-s. Now, Calculate the stress in the solid 50s after the sudden application of a fixed strain of 1%. Viscoelastic materials, such as amorphous polymers, semicrystalline polymers, biopolymers and even the living tissue and cells, can be modeled in order to determine their stress and strain or force and displacement interactions as well as their temporal dependencies. These models, which include the Maxwell model, the Kelvin–Voigt model, the standard linear solid model, and the Burger…
