High strain rate material properties
WebAug 2, 2024 · The material stiffness changed suddenly with strain rate, probably due to the chain relaxation. The chain motion kept up with the strain rate at low values, causing more significant deformation while presenting minor deformation at a higher rate . The stress-strain relationship and high strain rates caused higher flow stress but more softening. WebSep 30, 2011 · High strain rates—events that occur over a short period of time—tend to favor the elastic properties of materials. Elasticity is associated with load-bearing performance …
