Issued topics of Doctoral Study Program
The student will deal with selected aspects of advanced assessment of safety, reliability and durability of structures.
Tutor: Lehký David, prof. Ing., Ph.D.
Definition of optimisation model of a structure for: 1. design of a member, 2. strengthening of existing member, 3. design and strengthening of a structure. Calculation variant: stochastic, deterministic (according to the application class of the tasks), type of the restraining conditions, classes the target functions.
Tutor: Štěpánek Petr, prof. RNDr. Ing., CSc., dr. h. c.
The theme includes the development and application of new procedures in the issue of experimental analysis of engineering (railway) construction. It is expected focus on advanced mathematical techniques from the field of time and frequency domain in conjunction with the methods of artificial intelligence.
Tutor: Smutný Jaroslav, prof. Ing., Dr.
Both organic and anorganic fibres from waste raw materials can be used purposefully in construction fibre concretes with extracted aggregate and concrete recyclate. The comparison of physical-mechanical and durability characteristics of fibre concretes with and without loading can contribute to estimating lifetime and ductility behaviour of fibre concretes of different formulations.
Tutor: Stehlík Michal, doc. Ing., Ph.D.
In the Czech Republic is recycled annually 100 000 tons of glass waste. By crushing and cleaning of waste is created glass recyclate in a different factions. One of the potential application is the substitution of the coarse aggregate of concrete by glass recyclate. The results of a number of mechanical and physico-chemical tests without and after application of load shall decide on the use of concretes with the glass recyclate and shall help with the assessment of efficiency of production.
The theme is focused on study of dynamic behaviour of railway lines. The theme includes railway superstructure and railway subbase. Topic involves experiment and simulation techniques. The tema also includes application of a suitable modern mathematical apparatus for the evaluation of the railway lines parameters including of artificial intelligence methods using.
Student will create discrete model for coupled meachanical and transport problem for concrete. requirements: solid mathematical basis, ability to write/learn computer code (C++, Python)
Tutor: Eliáš Jan, prof. Ing., Ph.D.
Appropriate structural design from advanced building materials (including 3D printing materials) or rocks is conditioned by the ability of prediction of real response obtained by robust computational tools with implementation of proper failure models based on non-linear fracture mechanics.
Tutor: Keršner Zbyněk, prof. Ing., CSc.
With respect to the changing textural and structural characteristics of the rock massifs, it is highly probable that the development of the strength properties will be variable both vertically and horizontally. Suggested doctoral dissertation will be focused on investigation of the spatial variability of the triaxial compressive strength based on the testing of series of cores specimens from the selected massif.
Tutor: Krmíček Lukáš, prof. RNDr., Ph.D.
The dissertation is focused on development of simulation techniques for representation of physical processes in heterogeneous materials. The models are to be focused preferably on materials with irregular inner structure and at the same time, those that are relevant for civil engineering (concrete and similar composites). The processes to be modeled are fracture, transport phenomena and fatigue.
Tutor: Vořechovský Miroslav, prof. Ing., Ph.D.
The ability of concrete to repair its small cracks autonomously is called as self-healing. The main aim will be to quantify the self-curing effect based on fatigue and fracture-mechanical tests. The beams will be exposed to cyclic loading. From this a traditional S-N curve will be evaluated for each stress level. To quantify self-healing/curing effect and it influence on the residual fatigue life the tested specimen will scanned by CT tomography.
Tutor: Seitl Stanislav, doc. Ing., Ph.D.
Numerical and analytical modeling of fatigue in concerete and reinforced concrete
The use of stainless steel for bridge structures is relatively recent. Significant advances in the use of stainless steel in known. The degradation of properties and lifetime assessment of steel subjected to complex mechanical loading will be investigated. Experimental part of the proposal, evaluation of the input data for finite element software ANSYS i.e. a) S-N curve – smooth or with defined singular concentrator/notch, b) specimen with crack, threshold values, Paris’ law, stress ratios etc.
The Czech deep repository development programme resulted in identification of several localities with favourable geological conditions. The Czech concept of a deep repository construction targets on crystalline host rocks. The dissertation will be focused on fracture mechanics of geomaterials from the most favoured localities – Horka near Velké Meziříčí and Kraví hora near Dolní Rožínka.
The dissertation will be focused on determination of the failure mechanisms (sliding, shearing) of selected geomaterials during uniaxial and triaxial compression tests. The fracturing will be monitored by ultrasonic sounding and acoustic emission.
The theme is focused on the study of mechanics of railway structures. The theme includes static and dynamic analyses of the track with the special aim in speed increasing, modern elements of track and interoperability of railway infrastructure. Particular topics: - analytical and numerical methods for track analyses in the time and frequency domain - track-bridge interaction - continuous welded rail in curves of small radii - switches&crossings of a new generation
Tutor: Plášek Otto, doc. Ing., Ph.D.
Engineering structures subjected to loading may result in stresses exceeding the material strength and thus forcing the progressive damage. Computational modelling of quasi-brittle damage of a wide class of building materials and composites can be done using some nonlocal integral approaches. The student will pay attention to the verification and validation of available models and their potential improvements.
Tutor: Vala Jiří, prof. Ing., CSc.
Development of simulation and appximation methods for numerical analyses of problems featuring random variables. The bottom line is the development of advanced Monte Carlo strategies.
As geocomposites can be considered any geomaterials that are composed of petrographically, texturally and structurally different parts or zones. Suggested doctoral dissertation will be focused on investigation of the physico-mechanical properties (e.g., scleroscopic hardness, uniaxial and triaxial strength, indirect tensile strengths) of composite geomaterials.
Topic is focused on nonlinear modelling of concrete structures (e.g. bridges) taking into account uncertainties in material, load and environment.
Tutor: Novák Drahomír, prof. Ing., DrSc.
