Accounting for nonlinearity—constitutive relations improve modeling of fiber-reinforced polymer composites

By Lisa McDonald / October 8, 2021

Modeling the mechanical behavior of fiber-reinforced polymer composites is difficult because of their nonlinear response to external stimuli. Constitutive relations offer one way to account for the nonlinearity, and a team of researchers in Russia used this approach to model polymer composites designed as shut-off valves for pressure vessel service equipment.
