Parallel Microcracks based Ultrasensitive and Highly Stretchable Strain Sensors

Submitted by mortezaamjadi on

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

PhD with 5 Years of R&D and Industrial Experience, Actively Seeking a Job/Research Position in Acoustics and Vibration/Vibro-acoustics/Structural Dynamics/Noise and Vibration

Submitted by kiransahu on

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.

PhD studentship in Mechanics of Materials - Draping of non-crimp fabrics

Submitted by Helen Gardner on

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.

Mechanical Self-Assembly of a Strain-Engineered Flexible Layer: Wrinkling, Rolling, and Twisting

Submitted by zichen on

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.

We are trying to find out the work conjugate strain (and wryness) measures to T and M (stess and couple stress) and we know that in classical theory the conjugate strain measure is identified using the stress power, which appears in the power balance equation derived taking the inner product of the equation of motion with velocity. Please refer to the attached pdf for details.

1.  Given the equations of motion of Cosserat media (Eq 1 and 2 in attached pdf) how do we extend the procedure of calculating the stress power for Cosserat media?

JAM in 2015

Submitted by Yonggang Huang on

Thanks to the efforts of the associate editors and reviewers, JAM continues to publish very fast.  Among ~800 submissions in 2015, there are only 19 papers that are still under review as of February 1, 2016.  In addition, the acceptance rate continues to decline, to ~16% in 2015.
