=== Announcement ===
The [http://www.cvut.cz/en?set_language=en Czech Technical University in Prague] - [http://uceeb.cz/wp/?lang=en University Center for Energy Efficient Buildings] (UCEEB) offers '''seven post-doctoral positions''' in the field of modeling, simulation, assessment and optimization of multi-functional materials and structures.
 
'''Start date''': as soon as possible after 17 June 2013, until all positions are filled<br />
'''Contract duration''': until 30 June 2015 (with a critical evaluation after the first year)<br />
 
=== UCEEB in brief ===
Launched in October 2012, UCEEB is a newly established joint project of five faculties of the Czech Technical University in Prague. The mission of the Center is to perform high-level interdisciplinary research in the field of energy savings in buildings, utilizing a simulation-
based engineering approach. The theoretical research activities will be systematically complemented with experimental validation, performed in a full-scale setting. This will provide unique data on materials, structures, and systems of intelligent control, including on their impact
on the built and natural environment. Development of the Center is supported by the European Union through the Operational Program Research and Development for Innovations, project No. [http://www.risy.cz/cs/vyhledavace/programy-eu/detail?id=29021 CZ.1.05/2.1.00/03.0091].
 
=== Project organization ===

=== Research topics ===
 
==== Advanced cementitious materials ====
'''Mentor''': Zdeněk Bittnar
 
'''Description''': Fly ash is a waste material from thermally powered coal power plants. Czech republic and China have one of the highest fly ash/cement ratio. Applied research is needed to sustain increasing pressure on fly ash utilization. Coal co-combustion with organic materials is another challenging task to emerge. There is no single miracle solution for fly ash utilization but the most promising in terms of volume seems to be direct incorporation into concrete to form advanced cementitious materials. High volume fly ash concrete has been studied for decades showing utilization potential of fly ash, ways for improvement and pitfalls. In the majority of cases, no fly ash preprocessing exists in the form of grinding or particle separation. This open new ways for research and experiments.                 
Experimental part needs to be supported with simulations which quantify fly ash reactivity, depletion of capillary porosity, pozzolanic reaction, packing density, and evolution of compressive strength. Multiscale simulations provide suitable framework to address various phenomena in such multiscale concrete material. Virtual simulations should give directions of interesting areas and also to help reducing the amount of time-consuming experiments.
 
'''Specific requirements''': Cement chemistry, experience with concrete, experimental background, basic programming skills (in C/C++, Python, MATLAB or similar languages), background in simulations.
 
==== Drying and desalination of historical buildings using hydrophilic mineral wool ====
'''Mentor''': Robert Černý
 
'''Description''': Application of hydrophilic mineral wool materials for drying-out of flooded buildings and desalination of historical buildings will be analyzed by a combination of experimental and computational treatments. Complete sets of hygric, thermal and salt-related properties of hydrophilic mineral wool will be determined. The hygrothermal behavior of hydrophilic mineral wool materials in their supposed practical applications will be assessed in semi-scale experiments and computational service life prediction analyses.
 
'''Specific requirements''': Basic knowledge of transport phenomena in porous materials.
 
==== Low-energy building materials ====
'''Mentor''': Robert Černý
 
'''Description''': Low-energy building materials on the basis of industrial waste products will be investigated. At first, selection and analysis of potential raw materials will be done and the technology of sample preparation will be designed. Then, mechanical, hygric and durability properties of the new materials will be tested. Basic service life assessment of newly developed materials at their application for specific building structures will be performed.
 
'''Specific requirements''': Basic knowledge of experimental work in a physical or chemical laboratory.
 
==== Modeling of coupled cracking, creep and hygrothermal effects in construction materials ====
'''Mentor''': Milan Jirásek
 
'''Description''': The postdoctoral Fellow will work on a comprehensive model and simulation tool for the description of coupled thermo-hygro-mechanical effects in construction materials, in particular concrete. The model will take into account inelastic deformation processes (such as cracking or plastic yielding), viscous deformation processes, transport of moisture, and heat conduction. Particular attention will be paid to the mutual interaction between the mechanical problem and the heat and mass transfer, e.g. to the effect of temperature and humidity on creep, or to the effect of cracking on diffusivity and conductivity.
 
'''Specific requirements''': Experience with nonlinear finite element analysis, good background in viscoelasticity, plasticity and continuum damage mechanics, excellent programming skills (preferably C++ or similar object-oriented languages).
-->
 
==== Ultra High Performance Fiber-Reinforced Concrete (UHPFRC) in different loading conditions ====
'''Mentor''': Petr Konvalinka
 
'''Description''': The research work will be focused on experimental and numerical response of UHPFRC under intermediate strain rates developed in machine simulating impact. In addition mechanical parameters such as compressive, direct tensile and flexural strength and modulus of elasticity at high strain rates will be measured. The energy absorption capacity of both notched and un-notched beams subjected to quasi-static and impact loading will be compared.
 
'''Specific requirements''': Depending on the specific background of the candidate, experience in experimental and numerical investigation of mechanical parameters of civil engineering materials and structures.
 
==== Wood-based materials ====
'''Mentor''': Petr Kuklík
 
'''Description''': Evaluation of physical and mechanical properties of wood and wood-based products by destructive and non-destructive methods. Investigation of microstructure of wood and wood based materials. Development of wood-based materials. Modification of wood and wood-based materials in order to enhance their quality (UV-stability, durability, fire resistance, etc.).
 
'''Specific requirements''': Good knowledge of wood mechanics, experience with experimental work in laboratory, with emphasis on microscopic evaluation of wood and wood-based materials (the ability to work with electron microscope).
 
==== Numerical and experimental analysis of concrete performance in irradiated environment ====
'''Mentor''': Petr Štemberk
 
'''Description''': The primary aim of this topic is to assess the effect of concrete composition on its long-term shielding performance when exposed to various types of radiation. Specifically, the following issues will be targeted: the effect of nanoparticles in composition, the possibility of release of nanoparticles from concrete, the activity of released nanoparticles, the possible reduction of thickness of shielding walls, the minimization of crack during construction technology. The results will be applicable for nuclear facilities and hospitals.
 
'''Specific requirements''': Reasonable knowledge in the field. Basic programming skills in MATLAB.
 
==== Micromechanical modeling of thermal and acoustic insulation materials ====
'''Mentor''': Jan Zeman
 
'''Description''': The aim of this topic is to develop inexpensive analytical models to quantify e.g. thermal and acoustic properties of highly porous building materials utilized in energy-efficient buildings by exploring the available tools of computational homogenization or continuum micromechanics. To this purpose, the Fellow will develop models of micro- and nano-structure of such materials, investigate the relevant structure-property relationships or utilize these results to validate the model against available data and experiments performed at UCEEB (not necessarily by the Fellow). Attention can also be paid to a consistent incorporation of surface effects, so that the developed models will be applicable to nanocomposites.
 
'''Specific requirements''': Depending on the scientific background of the candidate, experience in numerical analysis and scientific computing, computational mechanics and high-performance computations, or in analytical homogenization.
