  • Sofronis, Petros; Robertson, Ian M. (Department of Theoretical and Applied Mechanics (UIUC), 2001-06)
    In-situ deformation studies in a transmission electron microscope equipped with an environmental cell have shown that solute hydrogen increases the velocity of dislocations, decreases the stacking-fault energy, and increases ...

    When a body is subject to simple internal constraints, the deformation gradient must belong to a certain manifold. This is in contrast to the situation in the unconstrained case, where the deformation gradient is in an ...

    We consider a recent experiment of Kundler and Finkelmann (1995), who subjected an aligned specimen of nematic elastomer to uniaxial extension and observed the formation of striped domains. Working with an energy density ...

    The remarkable ability of nematic elastomers to exist in multiple stable equilibrium configurations in the absence of force and energy cost is known as soft elasticity. Here, we determine all of the soft states that are ...
