Time-averaged coarse variables for multiscale dynamics

to appear in Quarterly of Applied Mathematics 

by Marshall Slemrod and Amit Acharya

Given an autonomous system of Ordinary Diff erential Equations without an a priori split into slow and fast components, we defi ne a strategy for producing a large class of `slow' variables (constants of fast motion) in a precise sense. The equation of evolution of any such slow variable is deduced. The strategy is to rewrite our system on an in finite dimensional "history" Hilbert space X and defi ne our coarse observation as a functional on X.

New inroads in an old subject: plasticity, from around the atomic to the macroscopic scale

(in Journal of the Mechanics and Physics of Solids)

Nonsingular, stressed, dislocation (wall) profiles are shown to be 1-d equilibria of a non-equilibrium theory of Field Dislocation Mechanics (FDM). It is also shown that such equilibrium profiles corresponding to a given level of load cannot generally serve as a traveling wave profile of the governing equation for other values of nearby constant load; however, one case of soft loading with a special form of the dislocation velocity law is demonstrated to have no ‘Peierls barrier’ in this sense. The analysis is facilitated by the formulation of a 1-d, scalar, time-dependent, Hamilton-Jacobi equation as an exact special case of the full 3-d FDM theory accounting for non-convex elastic energy, small, Nye-tensor dependent core energy, and possibly an energy contribution based on incompatible slip. Relevant nonlinear stability questions, including that of nucleation, are formulated in a non-equilibrium setting. Elementary averaging ideas show a singular perturbation structure in the evolution of the (unsymmetric) macroscopic plastic distortion, thus pointing to the possibility of predicting generally rate-insensitive slow response constrained to a tensorial ‘yield’ surface, while allowing fast excursions off it, even though only simple kinetic assumptions are employed in the microscopic FDM theory. The emergent small viscosity on averaging that serves as the small parameter for the perturbation structure is a robust, almost-geometric consequence of large gradients of slip in the dislocation core and the persistent presence of a large number of dislocations in the averaging volume. In the simplest approximation, the macroscopic yield criterion displays anisotropy based on the microscopic dislocation line and Burgers vector distribution, a dependence on the Laplacian of the incompatible slip tensor and a nonlocal term related to a Stokes-Helmholtz-curl projection of an ‘internal stress’ derived from the incompatible slip energy.

Journal Club Theme of August 2009: One-Way Wave Equations for Imaging, Mulitscale Modeling, and Absorbing BCs

(jointly with Siddharth Savadatti and Senganal Thirunavukkarasu)

Overview: The wave equation and its variants have been used to describe propagation of mechanical and electromagnetic disturbances in various media. The primary characteristic of these equations is that they propagate disturbances in all directions, i.e. in a two dimensional setting, wave equations have a 360-degree range of propagation angles. In contrast, one-way wave equations (OWWEs) propagate disturbances in a specified direction, while completely suppressing propagation in the opposite direction, i.e. in a two dimensional setting, OWWEs have a 180-degree range of propagation. We illustrate the difference between OWWEs and full wave equations in the animations below. The simulation shows the response to a point pulse load applied at the center of the layered domain. The top and bottom layers of the domain are identical while the middle layer has different properties.
