Elastic properties and failure behavior of disordered porous solids : a potential-of-mean-force-based lattice element approach
The effective mechanical properties of multiphase materials not only depend on the volume fraction and chemical composition of their constituents but also on details of their local texture. Yet, most homogenization methods do not take this texture effect into account. Understanding how local …

Multiscale Microstructural Investigation of the Ductile Phase Toughening Effect in a Bi-phase Tungsten Heavy Alloy
… been made in understanding and applying these multiphase materials systems. To that end, Pacific Northwest National Laboratory in collaboration with Virginia Tech have sought to understand and tailor the structure and properties of these materials to optimize them for service in fusion reactor …

Homogenization and elastic-plastic transitions in random and FGM microstructures
… the effective properties of heterogeneous materials with varying microstructures. Separation of scales (Micro (d), Meso(δ), Macro (L)), in these microstructures leads to the problem of determination of the Representative Volume Element (RVE) that corresponds to the effective properties of …

Designing Multiphase Step-Growth Polymers for Advanced Technologies: From Electromechanical Transducers to Additive Manufacturing
… polymers with novel monomers provided materials with tailored properties for emerging technologies. Specifically, multiphase materials (i.e., microphase separated block copolymers) exploit the synergistic relationship of combining polymers with disparate thermal and mechanical …

Synthesis and characterization of fluorinated cellulose derivatives
… properties of cellulose derivatives, in multiphase materials. Synthetic approaches included: 1) the replacement of hydroxyl groups on cellulose with fluorine using fluoride displacement chemistry, or direct, one step fluorination 2) the replacement of hydroxyl groups on hydroxypropyl …

Engineering properties of multiphase block copolymers
… system, for example, strictly one phase materials, with only one intermediate glass transition temperature, were obtained at block lengths of less than 10,000 g/mole. Two-phase copolymers resulted when blocks exceeding 20,000 g/mole were coupled. Copolymers comprised of intermediately …
