Computational structural mechanics with focus on soft tissues and wave propagation
Project and Job Description
Pulsation of the cerebral arteries is transmitted to the surrounding parenchyma, resulting in a characteristic cerebral motion and pressure distribution. Pathological changes in intracranial properties can lead to alterations of these parameters. The goal of this project is to associate such alterations with the onset of certain pathologies and to develop, together with a globally leading partner from the biomedical technology industry, a product prototype.

Job Description
The objective of this 6-month internship is to investigate and analyze downhole tool dynamics and the associated failures. Specifically, the selected candidate will be working on a) evaluation of various crack growth rules, b) probabilistic analysis of stochastic loading, and c) assessment of the effect of variability in material properties on structural durability using the Finite Element Method.
Requirements
1. Ph.D. candidacy in Mechanical Engineering, Aerospace Engineering, Civil Engineering, or Engineering Mechanics with a specialty in fatigue and facture mechanics.
2. In-depth understanding of continuum mechanics, elasticity, plasticity, finite element methods, fatigue of metals, fracture mechanics, shock and vibration, probabilistic and statistical methods, and materials engineering.
3. Extensive experience in numerical prediction and experimental characterization with regards to fracture mechanics is required.
4. Solid knowledge of ABAQUS is essential. Experience in developing user subroutines and Python scripts for ABAQUS is a plus.
5. Experience in large-scale, scientific coding is a bonus.
6. Excellent team spirit and communication skills
Raiway axle failures have been the starting point for the studies on fatigue. However, recent accidents and papers (see [1] by Hoddinott) have shown that corrosion-fatigue plays a significant role.
At PoliMi we have recently investigated this topic finding interesting results by corrosion-fatigue tests on small-scale specimens and, recently, a validation of the model by full-scale corrosion-fatigue tests (see papers [2-3]).
We are now participating to a EU project dedicated to new concepts for the inspection of railway axles (WOLAXIM project) and I am seeking for a candidate for a position of research assistant (February-December 2011) in this research field: the candidate will then be able to obtain a PhD position onto the same topic (PhD scholarship will start in Jan. 2012).
Candidates should have a background on fatigue, fracture mechanics and corrosion together with attitude for experimental activities and modelization.
Candidates can submit their Cv by e-mail (stefano.beretta@polimi.it) or directly go to the application web-page .

About CSML (http://www.kaust.edu.sa/tamerelsayed)
The focus of the Computational Solid Mechanics Laboratory (CSML) at KAUST is to develop
multi-scale constitutive models for metals and soft materials. The following summarizes current
research activities:
• Development of multi-scale constitutive models for nanocrystalline metals. The developed
models are capable of capturing distinctive features of nanocrystalline materials, such as the
grain size dependence both in classical Hall-Petch form for greater grain sizes (> 10-25nm)
and inverse Hall-Petch for finer grain sizes (< 10-25 nm).
• Development of constitutive models intended to reproduce damage in polymers caused by
high strain rate loading. Applications include the design of high-strength composites for
impact mitigation.
• Development of constitutive models for soils and rocks taking into account multiphase and
mixedphase flow, grain-grain and grain-liquid interaction under high-pressure, hightemperature
conditions. Applications include Enhanced Oil Recovery (EOR).
• Development of constitutive models intended to reproduce the damage of biological soft
tissues induced by bubble cavitation, growth, and coalescence. Potential benefits to industry,
the medical and defense communities include: the ability to derive a sound mechanistic and
quantitative understanding of traumatic head injury leading to improvements in operative
management and post-traumatic care; and the ability to predict the lethality of traumatic injury
to the head leading to improvements in helmet and other protective head-gear design and
increased survivability during accidents.
The developed constitutive models are invaluable parts of predictive simulation methods, which
can be used in designing tailor-made materials with superior properties. The long-term goal is to
reduce the amount of experimental efforts, which are expensive and time consuming with the
developed simulation tools.

Department of Materials Science and Engineering, MIT
A postdoctoral position is available in the Department of Materials Science and Engineering (DMSE) at MIT, Cambridge, Gradečak Laboratory. The goal of this project is to combine in situ transmission microscopy (TEM) and atomistic modeling (separate but related project led by Prof. Michael Demkowicz, DMSE) to determine the relationship between the structure of “weakest link” interfaces in Ni-base superalloys and the conditions under which they undergo ductile-to-brittle transitions in the presence of H. This information may then be used to a) improve lifetime predictions based on analysis of microstructures and b) enable the selection of new alloys with reduced susceptibility to H embrittlement by specifying grain boundary content.
We will carry out in situ TEM observations of the H-induced failure of the microstructural features during mechanical loading. In-situ TEM and scanning electron microscopy (SEM) coupled with high-resolution chemical analysis will be used to investigate the sample response as a function of temperature, H exposure, and straining. First, H-induced decohesion and dislocation formation/motion will be investigated in a set of model alloys using in-situ TEM straining in combination with heating. H accumulation at precipitates and possible hydride phase formation will be investigated using energy dispersive X-ray spectroscopy (EDS) and electron energy loss spectroscopy (EELS) and aberration-corrected scanning transmission electron microscopy. Finally, gas and fluid cell compatible holders (with possible straining capabilities) will be used to investigate in-situ sample response to hydrogen environments.
The candidate should have a PhD in Materials Science, Physics, or equivalent, and have extensive experience with materials characterization by TEM. Good communication skills in spoken and written English are essential. To apply, please send a cover letter and CV including contact information for three references to:
