Fatigue-resistant hydrogels: Principles, Experiments, and Applications

Shaoting Lin, Xuanhe Zhao

1.     Introduction

Willing to share the work done in my Ph.D. thesis ("An efficient numerical framework for capturing localised 3D stress fields in laminated composites). The basic code (written in FORTRAN 90) is available on GITHUB (Check the following link). 

EML Webinar on July 1, 2020 will be given by Prof. Chiara Daraio at Caltech via Zoom meeting. Discussion leader: Teng Li, University of Maryland.

Dear Colleagues,

In the last twenty years, tribology and nonlinear dynamics have included several major contributions related to key topics such as rough contact, friction, damping mechanisms, and dynamical behaviour of nonlinear systems, which are paving the way for future engineering challenges. The two fields are largely intertwined as, among the others, contact nonlinearities are almost omnipresent in any technical application ranging from the development of NEMS/MEMS to bioengineering, automotive, civil/mechanical industry, and aerospace.

The USACM is happy to announce a virtual seminar this week on Thursday, June 25th at 3pm Eastern.  The title of the seminar is "Data-Driven Turbulence Modeling and Simulation: From RANS to LES".  An abstract of the talk is available here:

We have a number of seats available to anyone interested.  We just ask attendees to register at this page:

EML Webinar on June 24, 2020 will be given by Prof. Michael Dickey, NC State University. Discussion leader: Hanqing Jiang, Arizona State University.

Freeze casting presents exciting new avenues towards high performance materials with aligned pore structures.

Bone scaffolds, highly elastic composites and nacre mimetic materials can all be produced by means of freeze casting methods. 

This comprehensive review presents recent development in terms of materials and processing

Stroke is #1 cause of long-term disability and #4 cause of death in the US. Most of the patients are not treated in time due to unavailability of professional neurosurgeons on site. We have developed a ferromagnetic soft continuum robot for tele-operated and autonomous navigation and treatment of strokes. The foundation is the hard-magnetic elastica theory which offers a fast and accurate prediction of the large deformation of the ferromagnetic soft continuum robot.

Twenty years in since their introduction, it is now plain that the regularized formulations dubbed as phase-field of the variational theory of brittle fracture of Francfort and Marigo (1998) provide a powerful macroscopic theory to describe and predict the propagation of cracks in linear elastic brittle materials under arbitrary quasistatic loading conditions. Over the past ten years, the ability of the phase-field approach to also possibly describe and predict crack nucleation has been under intense investigation.

Dear colleagues,

This paper on  comparison between frontal and bulk polymerization of polymer matrix compositres using a non-dimensional solver is published in Composite Science and Technology. If you would like to take a look, full paper is avaiable at the publisher and Researchgate.

Abstract:

https://doi.org/10.1039/D0TB00896F It is my privilege and honor to be highlighted as the Journal of Material Chemistry B's Emerging Investigators for 2020. Together with our group's young budding scientists, Chenxi Zhai, Tianjiao Li, and Haoyuan Shi, we review the discovery and design of next-generation bio-inspired materials by harnessing the virtual space in materials design: materials omics (materiomics), materials informatics, computational modelling and simulations, artificial intelligence (AI), and big data.

This is the preprint of an article that will appear in Soft Matter (doi.org/10.1039/D0SM00845A)

Statistical Mechanical Analysis of the Electromechanical Coupling in an Electrically-Responsive Polymer Chain

Matthew Grasinger and Kaushik Dayal
Carnegie Mellon University

The USACM has established a virtual seminar series that will run for six weeks over the course of this summer.  Exact dates and times will vary each week, but a full listing of the speakers is available here:

https://www.usacm.org/seminar-series

The series features young computational mechanicians from across the US.  The talks are an opportunity for these young scientists to showcase their research activities during a period in which so many conferences and meetings are being cancelled or postponed.

Dear iMechanica Community: 

Dear iMechanicians,

I hope the present work is of interest to you. We present a new formulation for resolving the electrochemical-diffusion interface in hydrogen embrittlement modelling
