(Yang et al Adv. Funct. Mater. 2019, 1901721). In our new paper, strong adhesion is achieved in integrated structures of a hydrogel and an elastomer extrusion-printed in arbitrary sequence.

Many materials of everyday use are fibrous and their strength is important in most applications. In this work we study the dependence of the strength of random fiber networks on structural parameters such as the network density, cross-link density, fiber tortuosity, and the strength of the inter-fiber cross-links. Athermal networks of cellular and fibrous type are considered. We conclude that the network strength scales linearly with the cross-link number density and with the cross-link strength for a broad range of network parameters, and for both types of networks considered.

The College of Engineering and Science at Louisiana Tech University is seeking self-motivated candidates for a Graduate Research Assistant (Ph.D. student) position, with the earliest starting date in Fall 2019.

IMPACT is an international Multiscale Materials Testing Research Group at Tampere University. Our work focuses on microscopic and macroscopic mechanical testing of materials at different strain rates and temperatures. We focus on improving the basic scientific understanding of material behaviour under extreme conditions and solving practical industrial problems involving high rate material deformation. IMPACT is looking to hire a Doctoral Researcher (PhD student) in the field of Materials Science to work on micromechanics of materials studied under extreme deformation conditions.

1. Introduction

PhD positions are available at the University of Minnesota in the group of Prof. Stefano Gonella. The positions are in the general area of mechanics and physics of solids, with emphasis on mechanical metamaterials. The position ideally starts in fall 2019, although a later start date (for example, in January 2020) can be considered.

Topics of current interest are:

1) Topological metamaterials;

2) Nonlinear and soft metamaterials;

3) Tunable and programmable metastructures.
