IMECE 2015: Student Travel Awards and Best Paper Contest

Dear IMECE Attendees:

The Applied Mechanics Executive Committee (AMD-EC) is pleased to announce the 2015 IMECE student travel award and best paper competition.

On the modeling of asymmetric yield functions

In the context of metal plasticity, the yield function of a metal polycrystal is its most complex macro-characteristic. Letting aside the questions of kinematic or distortional hardening, the basic problem is geometric in nature: to design a family of convex surfaces capable of reproducing a wide range of experimental, or theoretically predicted data. While many satisfactory solutions have been proposed for the modeling of symmetric (with respect to the origin of the stress space) yield functions, the more general case of asymmetric functions has not witnessed comparable progress.

Is energy conservation satisfied in the current deformation application schemes in molecular dynamic simulations?

In our recent paper, we examined the energy conservation for the current schemes of applying active deformation in molecular dynamics (MD) simulations. Specifically, two methods are examined. One is scaling the dimension of the simulation box and the atom positions via an affine transformation, suitable for the periodic system. The other is moving the rigid walls that interact with the atoms in the system, suitable for the non-periodic system.

2nd Call for Abstracts: USNCCM13 Minisymposium 414 on Recent Advances in Mesh Adaptivity for Inelasticity, Damage, Crack Propagation and Failure.

In this minisymposium we seek to highlight challenging problems in computational solid mechanics that require mesh adaptation methods for their solution. We focus on the finite element method and works that address large deformations and the accompanying inelasticity, damage, crack propagation and failure. Discussion will center on Lagrangian descriptions and determining the necessary computational components to resolve, preserve, and evolve the fields that govern these processes. Prototypical material systems may include, but are not limited to, ductile metals and biomaterials.

some discussion and questions on Fineberg's beautiful experiments on dry friction

As many of you I am very intrigued by Fineberg's experiments on friction, published several times in Nature and Science (see ref. list below). I am trying to develop some (simple) models from a different perspective than what most people are trying to do (full dynamic simulations including all possible viscoelastic, rate-state dependence, etc.), main reason being that I think Coulomb law is still the basis for most engineering calculation.

Discussion of fracture paper #10 - Searching for the length scale of stress corrosion

According to the Swedish Plant Inspectorate the major part of all reported fracture related failures in Sweden are due to stress corrosion. I guess it is more or less a reality everywhere. The association with accidents is probably because it comes without warning and usually at surprisingly low loads. Just a mm sized spot of decomposing grease is enough to create a locally extremely acid environment. In an otherwise friendly environment this often not even considered as a possibility by the designer.
