It is well known that a state of pure shear has distinct sets of basis vectors or coordinate systems: the principal axes, in which the stress σ is diagonal, and pure shear bases, in which diagσ = 0. The latter is commonly taken as the definition of pure shear, although a state of pure shear is more generally defined by trσ = 0. New results are presented that characterize all possible pure shear...
Elastic field coupling to solute concentration is known to produce dislocationdriven impurity segregation. Recent reports detailing the distribution of boron around edge dislocations in B2-ordered FeAl indicate that nonlinear coupling of species concentration and elastic strain to the chemical potential must be considered to assess the magnitude of boron segregation around edge dislocations. On...
Fluctuations of the instantaneous local Lagrangian strain epsilon(ij)(r,t), measured with respect to a static "reference" lattice, are used to obtain accurate estimates of the elastic constants of model solids from atomistic computer simulations. The measured strains are systematically coarse-grained by averaging them within subsystems (of size L(b)) of a system (of total size L) in the canonic...
Senspectra is a computationally augmented physical modeling toolkit designed for sensing and visualization of structural strain. The system functions as a distributed sensor network consisting of nodes, embedded with computational capabilities and a full spectrum LED, which communicate to neighbor nodes to determine a network topology through a system of flexible joints. Each joint, while servi...
