A Plasticity Theory of Metals Based on the Dislocation Substructures
A cyclic plasticity model developed from the microscopic deformation mechanism of metals is suggested. In the development of such a mechanistic model, the dislocation substructure of metals under different loadings is studied. Based on the observed substructure, the deformation mechanism of metals …

Packing of particles during softening and melting process.
Softening deformation of iron ore in the form of sinter, pellet, and lump ore in the cohesive zone of an ironmaking blast furnace is an important phenomenon that has a significant effect on gas permeability and consequently blast furnace production efficiency. The macroscopic softening deformation …

Micromechanics of Granular Media: A Fundamental Study of Interphase Systems
… systems. The interphase region influences load-deformation behavior of the entire composite system. However, mechanisms that control the mechanical behavior of the interphase region and, in turn, control the composite structure behavior, are not clearly understood. Few relationships exist for …

Passive biomimetic actuators : the role of material architecture
… a hidden length scale allowing large directed deformations. By comparing the area expansion in all lattices, we were able to show that less convex cells are prone to achieve larger area expansions, but the direction in which the material expands is variable and depends on the local cell’s …

Modeling mechanical properties – linking atomistics to continuum
… simulations and experiments is used to study the microscopic deformation mechanisms of materials. Atomic scale simulation tools include molecular dynamics and density functional theory. The experiments involve uniaxial tension and compression tests on: (a) single crystals of low stacking fault …
