Cauchy-born Rule and the Stability of Crystalline Solids:Dynamic Problems
Cauchy-born Rule the Stability Crystalline Solids Dynamic Problems
2012/8/7
We study continuum and atomistic models for the elastodynamics of crystalline
solids at zero temperature. We establish sharp criterion for the regime of validity of the
nonlinear elastic wave equati...
An Interrupted Dynamic Tensile Testing for Pure Copper Bars
interrupted tension high strain rate constitutive model necking void evolution pure copper bar
2012/9/24
A high-speed tensile fac ility (HSTF) invented by us was applied to interrupt tests for pure copper bars controlled locally at different levels of elongatio n. It was realized to isolate and identify ...
Incubation-time Based Approach for Dynamic Yielding of Metals
dynamic yielding incubation-time approach failure criteria
2012/9/24
Transition of the materials from elastic to plastic state is modeled by incubation-time based criterion. This approach is similar to the structural -temporal theory for brittle solids fracture develop...
Evidence of coexistence of change of caged dynamics at Tg and the dynamic transition at Td in solvated proteins
hydrated protein, solvated proteins, aqueous mixtures, carbohydrates, caged dynamics, glass transition
2011/9/14
Mössbauer spectroscopy and neutron scattering measurements on proteins embedded in solvents including water and aqueous mixtures have emphasized the observation of the distinctive temperature dep...
