How safe are metal-on-metal hip implants? and are ceramic-on-ceramic safer? Or we will discover soon they are not?Submitted by Mike Ciavarella on Sun, 2013-09-29 22:49.
Would you believe this story?
To me, that metal - on - metal had large friction, especially with the newest designs, it was clear from the old Sir Charnley studies in Leeds in 1950s published in his gold book.
Anyway, when I looked at ceramic on ceramic joints, I also found evidence of increased friction. Maybe ceramic debris is less toxic?
Please comment. What can we do outside USA to improve the situation?

Fixation and Mechanical Properties of Implanted Cartilage Replacements - Overview of three recently published papersSubmitted by Ali_Vahdati on Sun, 2013-09-29 18:08.
full-thickness cartilage lesions of the knee caused by trauma, disease or joint
instability are a common disorder affecting people of all ages. Implanted
cartilage replacements (ICR) have the potential to overcome the limitations of
conventional treatment methods and are a promising approach to restore
functionality of the joint. In spite of some success in engineering
cartilaginous tissue, inferior biomechanical and biochemical properties of ICR
compared to native articular cartilage (AC) and inadequate quality of fixation

Join us at the 5th International Conference on Mechanics of Biomaterials and Tissues, reviewing the very latest on the mechanics of biological, natural and biologically inspired materials, and those materials used to replace them in the human body.
The Department of Mechanical Science and Engineering (MechSE) at the University of Illinois at Urbana-Champaign invites applications for faculty positions at all levels in Solid Mechanics, broadly defined, with particular emphasis on research that is experimental in nature. MechSE at Illinois has a strong tradition in solid mechanics, and offers a BS degree in Engineering Mechanics and MS/PhD programs in Theoretical and Applied Mechanics, as well as BS, MS, and PhD degrees in Mechanical Engineering.
I would like to invite you on behalf of myself, Prof. Tahir Cagin (Texas A&M) and Prof. Akhtar Khan (University of Maryland) to contribute to a newly added mini-symvposium to the International Symposium of Plasticity to take place 3-8 January 2013 at Bahamas Island; more detailed information of the event is listed below.
a PhD student ship is available for UK/EU nationals (ONLY) to develop a Finite Element model of the rolling
operation to predict the behaviour of surface defects on the rolled
material during hot rolling of steels. The effects of geometrical parameters along with the material
properties and the rolling geometry, such as bite angle, on the behaviour of
the surface defects during rolling will be investigated. The
project is partially funded by Tata Steel Europe,
a research experience on application of ABAQUS in large deformation modelling and metallurgy of steels is necessary.
Position Filled. (Postdoctoral Position Opening at the University of Michigan in Experimental Mechanics)Submitted by Sam Daly on Wed, 2013-09-25 00:22.
--- Position Filled. No longer accepting applications. ---
Prof. Samantha Daly at the University of Michigan is seeking candidates for a one-year post-doctoral position. This position is renewable depending on performance. The project is a joint effort with other U-M research groups to integrate advanced analysis and materials research in a new framework for capturing materials information, where computationally efficient reduced order random field descriptors are used to capture microstructural and property information. The post-doctoral position will focus on the experimental aspects of this work, specifically the small-scale characterization of polycrystalline deformation in alpha-titanium alloys.
The Department of Mechanical Engineering invites outstanding applicants in all areas of
Mechanical Engineering for tenure-track positions at the level of Assistant Professor beginning
Fall 2014. The Department of Mechanical Engineering is multi-disciplinary with strong research
programs in Biomechanics, Robotics and Control, MEMs and Nanotechnology, Thermo-fluid
Sciences and Energy, Bioacoustics, and Materials. The department is further strengthened by its
affiliation with the Photonics Center, the Division of Materials Science and Engineering, The
Division of Systems Engineering, and the Fraunhofer USA Center for Manufacturing Innovation.

The 20th European Conference on Fracture (ECF20) to be held at Trondheim, in Norway on 30 June – 4 July 2014.Submitted by Zhiliang Zhang on Mon, 2013-09-23 20:52.
The 20th European Conference on Fracture (www.ecf20.no) will be held at Trondheim, in Norway on 30 June - 4 July 2014. We are inviting abstracts in the areas of fracture and fatigue at all scales! The deadline for abstract submission is 4 October, 2013.
An ECF summer school on Fracture Modeling and Assessment will be arranged two days before the conference. The summer school is mainly aimed at PhD students, young scientists and engineers, but is naturally open to everybody. Participants will become acquainted with general aspects, emerging fields and recent practical applications of fracture mechanics.
Can you please suggest me some basic papers and references in multiscale modeling and simulation of materials. I am quite naive in this field. I have some exposure to solid mechanics and finite element techniques. I understand that I need to study molecular dynamic simulations also, where again I need advice for basic references. I would be thankful for your help.
Thanks and regards,
I am looking for a new Ph.D. student to work on discretization of nonlinear elasticity using geometric and topological ideas. Requirements for this position are a strong background in solid mechanics and some background in differential geometry and analysis. If interested please email me your CV.

The group of Mechanics of Solids and Structures at the School of Engineering at the University of Brescia, Italy has two openings for Ph.D. positions. The appointment will begin on January 1st 2014 for three full years.
Positions are in the following areas:
1. multi scale and multi physics modeling, particularly but not limited to diffusion of species in solids (H-embrittlement, energy storage materials, mechano-biology)
2. propagating processes in solids, particularly but not limited to fracture propagation (dynamic, quasi-static, hydraulic), phase segregation, elastic or inelastic waves in multilayered materials, cloaking.
The Department of Engineering Science and Mechanics (ESM) at Virginia Tech seeks applicants for a tenure-track faculty position as an experimentalist in one of the general areas of dynamical systems, fluid mechanics, or solid mechanics. The appointment will be at the rank of assistant professor. Successful applicants are required to have a doctoral degree in a relevant field of science or engineering, and are expected to: have a strong and broad scholarly interest in the mechanical sciences, develop and maintain an active, externally-funded research program, and teach at the undergraduate and graduate levels. Intellectual depth is more important than the specific area of specialization.
