    Virtual Field Characterization for Ratcheting Effect Under Cyclic Loading

    Ratcheting is an important mechanical behavior of metals and alloys, which is caused by the repeated accumulations of tensile and compressive strain in circle load. However, the current characterization method...

    The Need to Use Generalized Continuum Mechanics to Model 3D Textile Composite Forming

    3D textile composite reinforcements can generally be modelled as continuum media. It is shown that the classical continuum mechanics of Cauchy is insufficient to depict the mechanical behavior of textile mater...

    Atomistic Studies of Generic Tilt Grain Boundary Structures

    We investigate the atomic-scale structures of high-sigma (∑) tilt grain boundaries in aluminum using lattice statics calculations. In particular, we examine the efficacy of the structural unit model (SUM) in t...

    Investigation of the annealing texture evolution in hafnium

    This article presents a study of the evolution of the annealing texture in hafnium, as measured by electron backscattering diffraction patterns (EBSPs). It was found that the annealing texture of asreceived ex...

    Epitaxial Growth of GaN on Lattice-Matched Hafnium Substrates

    A method of producing epitaxial GaN on single-crystal Hf has been developed. The metal substrate is formed by a strain-anneal process yielding macroscopic (5-mm) grain sizes, followed by polishing, chemical et...
