Hi all, 

Just wanted to share that the first issue of Matter was released last week. Matter is a new materials science journal from Cell Press. Our goal is to be a high impact offering, on par with Nature Materials. Check out our first issue here:

I attach a Letter I sent to the Editor of a tribology journal, concerning adhesion of rough surfaces. 

I contend that some "criteria" that have been proposed based on extrapolation of numerical results are due to the limitations in present numerical sophisticated rough contact simulations, which only span at most 3 orders of magnitude of wavelengths, so typically people simulate from nanometer to micrometer scale.

Hello,

More detailed results on the void growth in single and dual phase titanium alloys.

Highlights:

A recent study reviews achievements made in the determination of the size‐dependent mechanical properties of nanowires. Covering both measurement techniques and computational approaches, data reported in the literature are summarized for a variety of nanowires.

In this work, we present concepts that allow controlled introduction of buckling and twisting deformations to the mechanically guided assembly of 3D mesostructures.

The winner of the 2019 Robert J. Melosh Medal is Dewen Yushu (University of Notre Dame), who presented the paper "The data-driven multiscale multigrid solver, preconditioner and reduced-order model."

Congratulations also to the other finalists! They are listed below, with their respective papers:

Siddhant Kumar, California Institute of Technology and ETH Zurich "Enhanced local maximum-entropy approximation for stable meshfree simulations;"

Dear iMechanica members,

I have recently proposed a novel finite element framework for computational solid mechanics. I hope you find it interesting. I appreciate any feedback.

Towards addressing some long-standing issues in performing explicit elastodynamic simulations of incompressible hyperelastic and elastoplastic material models, finite element formulations based on Bézier elements are developed. The formulations are based on quadratic Bézier triangular and tetrahedral elements.
