We present a systematic approach to deal with the modelling and analysis of the cracked rotating shafts behaviour. We begin by revisiting the problem of modelling the breathing mechanism of the crack.

Here we consider an original approach based on the form we give to the energy of the system and then identify the mechanism parameters using 3D computations with unilateral contact conditions on the crack lips.

Herein, we report a theoretical study of polymeric nanocomposites to provide physical insight into complex material systems in elastic regions. A self-consistent scheme is adopted to predict piezoresistive characteristics, and the effects of the interface and of tunneling on the effective piezoresistive and electrical properties of the nanocomposites are simulated. The overall piezoresistive sensitivity is predicted to be reduced when the lower interfacial resistivity of multi-walled carbon nanotubes (MWCNTs) and the higher effective stiffness of nanocomposites are considered.

I am looking for talented, self-motivated, and enthusiastic students with MSc degree in mechanical or materials engineering. Students with a background in any of the following areas are recommended to apply:

• Solid mechanics and finite element modelling of materials
• Crystal plasticity modelling of polycrystals
• Materials characterization

The selected candidates are expected to start no later than January 2018.  

In this paper, we studied the strain rate dependent failure properties of human diaphragm tissue using uniaxial tensile testing at four strain rates, i.e. 0.0015/s, 65/s, 130/s and 190/s. The custom made quasi-satatic and drop tower based dynamic test setups was used to conduct the tests uptill 200/s strain rate.

A postdoctoral position is available in the area of characterizing the mechanical properties of biological materials. The primary objective is to use experimental methods to investigate the mechanical response of soft tissues. The candidate is responsible to develop and carry out the experiments, analyze the results, and develop computational models to understand the measured properties. Please note that applicants must have previous experience with conducting experiments on soft tissues or soft materials and they are required to have a Ph.D.
