NSF - Mechanics of Materials and Structures

Dear colleagues,

There have been two changes at NSF that do affect the imechanica community. I would like to bring these to your attention.

INTERNSHIP SIMULATION OF LARGE SCALE FRACTURE UNIVERSITY OF LUXEMBOURG (variational theory)

Dear All, Please see the attachment. We are looking only for an MSc student intern who is enrolled in a Higher Education Institution (in the European Union). The topic is the variational theory of fracture for microchip manufacturing. Connections to a relevant company in France are possible. Please see also, in the attachment, our 2014 Computational Mechanics Lab Report and our best wishes for 2015. Regards, Stéphane and the team. Best wishes for 2015: http://hdl.handle.net/10993/19425

Post-doctoral position in Computational Mechanics

One post-doctoral Research Associate in Computational Mechanics is sought to work on the Croatian Science Foundation project No. 1631 'Configuration-dependent Approximation in Non-linear Finite-element Analysis of Structures' on a full-time fixed-term contract for the duration of three years and six months or until the project financing has expired.

The project explores the configuration-dependent interpolation as a novel, unorthodox and remarkably promising expansion of the framework within which the non-linear finite-element method has been traditionally contained. The basic idea underlying the project stems from an apparent disparity between the rather advanced extensions of the traditional linear finite-element principles to non-linear problems and the fact that the key finite-element concept – that of interpolation of the unknown functions – is surprisingly kept mostly constant, i.e. configuration-independent. Enabling the finite-element approximation to become configuration-dependent is motivated by the existing need to improve the current non-linear finite-element procedures, in particular for mechanical problems defined on non-linear manifolds. This principle is presented as the general concept providing viable novel development paradigm with obvious benefits for a wider class of mechanical problems. The configuration-dependent approximation to be designed shall obey the essential convergence requirements, with its extra flexibility (arising from the potential of the new approximation to vary with the configuration) employed to improve the solution in some clearly defined manner.

More detail in the attachment.

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.

The rheology of non-dilute dispersions of highly deformable viscoelastic particles in Newtonian fluids

Abstract: We present a model for the rheological behaviour of non-dilute suspensions of initially spherical viscoelastic particles in viscous fluids under uniform Stokes flow conditions. The particles are assumed to be neutrally buoyant Kelvin–Voigt solids undergoing time-dependent finite deformations and exhibiting generalized neo-Hookean behaviour in their purely elastic limit. We investigate the effects of the shape dynamics and constitutive properties of the viscoelastic particles on the macroscopic rheological behaviour of the suspensions.

Unravelling the physics of size-dependent dislocation-mediated plasticity

Size-affected dislocation-mediated plasticity is important in a wide range of materials and technologies. The question of how to explain and predict the effect of size on the properties and response of materials has been at the forefront of mechanics and materials research.

Open Postdoctoral Position in Computational Science and Engineering

The University of Notre Dame, Center for Shock Wave-processing of Advanced Reactive Materials (C-SWARM), is seeking a highly qualified candidate for a Postdoctoral Research Associate position in the area of computational mechanics/physics. C-SWARM is a newly established center of the emerging field of predictive science. The main mission of C-SWARM is to predict shock conditions under which new materials can be synthesized using predictive computational models that are verified and validated with quantified uncertainty on future high-performance Exascale computer platforms.

Two-phase solid–liquid coexistence of Ni, Cu, and Al by molecular dynamics simulations using the modified embedded-atom method

The two-phase solid–liquid coexisting structures of Ni, Cu, and Al are studied by molecular dynamics (MD) simulations using the second nearest-neighbor (2NN) modified-embedded atom method (MEAM) potential. For this purpose, the existing 2NN-MEAM parameters for Ni and Cu were modified to make them suitable for the MD simulations of the problems related to the two-phase solid–liquid coexistence of these elements.

2nd Workshop: Impact of mechanical and thermal loads on the long term stability of PV modules, 3 February 2015, Hannover

 

After the successful first edition organized by ISFH and held in Hamelin (Germany) in November 2013, ISD hosts the second edition of the workshop entitled “Impact of mechanical and thermal loads on the long term stability of PV modules”. On behalf of the ISD-ISFH consortium, we are pleased to invite you to participate at this event. This is a great opportunity for meeting colleagues active in this area and discussing new ideas and establishing links for future cooperation.

A Review of Quantitative Phase-Field Crystal Modeling of Solid–Liquid Structures

Phase-field crystal (PFC) is a model with atomistic-scale details acting on diffusive time scales. PFC uses the density field as its order parameter, which takes a constant value in the liquid phase and a periodic function in the solid phase. PFC naturally takes into account elasticity, solid–liquid interface free energy, surface anisotropy, and grain boundary free energy by using this single-order parameter in modeling of coexisting solid–liquid structures.

Effects of geometrical and mechanical properties of fiber and matrix on composite fracture toughness

Composites reinforced by thinner fibers are intensively studied in recent years and expected to have better
mechanical properties. With development of nanotechnology, the diameter of fiber can be as thin as
several nanometers, such as nanofibers and nanotubes. Then, do these thinner fibers definitely result in
composites with better mechanical properties? In this paper, the toughening effect of reinforcing fibers in
composites is investigated based on the three-level failure analysis model. It is found that thinner

Submissions to JAM have almost doubled

The submission to JAM in 2013 was ~42 manuscripts/month.  Probably because of its rapid review process (1st round of review ~ 10 days, and 2nd round of review ~24 days including authors' revision time) and rapid publication (online within 48 hours after acceptance), the monthly submission is nearly doubled now.  For example, the submission in December, 2014 is 78 in a single month.
