Ph.D. level, staff scientist and/or postdoctoral positions in otolaryngology/mechanical engineering with foci on development of several types of surgical tools and biophysical studies are available in an interdisciplinary team of a NIH-funded project headed by Professor Anil Lalwani, MD, and Professor Jeffrey Kysar, PhD, at Columbia University, in New York, New York, USA. The successful applicants will join a dynamic, interdisciplinary group of researchers including otolaryngologists, mechanical engineers, clinicians, and neuroscientists.

There is an increasing demand for flexible, skin-attachable, and wearable strain sensors due to their various potential applications. However, achieving strain sensors with both high
sensitivity and high stretchability is still a grand challenge. Here, we propose highly sensitive and stretchable strain sensors based on the reversible microcrack formation in composite thin
films. Controllable parallel microcracks are generated in graphite thin films coated on elastomer films. Sensors made of graphite thin films with short microcracks possess high

I am an experienced professional in structure borne sound, structural and machinery dynamics, vibro-acoustics, and now actively looking for a career opportunity in R&Ds or in Industries. Ph.D. in acoustics & vibration, around 5 years of work experience in R&Ds and Industries, published articles in reputed international Journals and Conferences with modelling, simulation, testing and analysis experience backed by relevant course-works. In achieving this, I have shown myself to be self-motivated, committed and determined in arriving at my goals.

The aim of the PhD is to develop a micromechanical model for forming of non-crimp fabrics (NCFs), and use this to optimise the pre-forming process for manufacture of complex shapes. The work will include both experimental work and finite element modelling. The work will benefit from close links with industrial partners Formax (manufacturer of NCFs), Simulia (developers of Abaqus forming simulation tools) and Jaguar Land Rover.

Self-shaping of curved structures, especially those involving flexible thin layers, is attracting increasing attention because of their broad potential applications in, e.g., nanoelectromechanical andmicroelectromechanical systems, sensors, artificial skins, stretchable electronics, robotics, and drug delivery.

The 21st International Conference on Wear of Materials will take place in California, USA from the 26-30 March 2017.

In this review of particularly readworthy papers in EFM, I have selected a paper about the tearing of large ductile plates, namely:

”Cohesive zone modeling and calibration for mode I tearing of large ductile plates”  by P.B. Woelke, M.D. Shields, J.W. Hutchinson, Engineering Fracture Mechanics, 147 (2015) 293-305.
