Opis:
This paper presents a framework for the reliability characteristics estimation on the experimental data. The framework consists of the set of failures, the experimental data sources, the set of reliability characteristics, the estimation methods, the estimation goodness tests and the expert system supporting estimation and statistical inference processes. The experimental data was obtained with two main theoretical means: control theory and diagnostics. It has been observed that changes of the functioning condition potential could serve to determine the symptoms of transient (momentary) failures and the changes in the potential of the technical condition to determine the symptoms of parametric faults. Such an information is sufficient to calculate reliability characteristics before dangerous catastrophic failures occur and to calculate reliability characteristics for single object without having to deal with a numerous set of objects. The set of reliability characteristics models consists of the analysed failures combination and distribution functions used in the reliability engineering. The set of estimation methods includes analytical and numerical ones. The proposed expert system supporting estimation and statistical inference processes consists of data base (the experimental data), rule base and inferring machine.

Opis:
The problem of dilation is discussed in the context of classical Cam-Clay model, which was developed on the basis of a specific assumption regarding the plastic work. This assumption leads to a special form of the dilation function, from which a shape of yield function is derived. The above mentioned assumption is compared with the results of the triaxial tests, performed on the model “Skarpa” sand. It is shown that the Cam-Clay approach is not realistic, as it is based on the assumption which is not consistent with experimental data. Some general considerations and discussion of this problem are also presented.

Opis:
The aim of this article is to compare experimentally determined strains of sand with theoretical calculations made on the base of the theory of hypoplasticity. During the study `Skarpa' sand was examined in the triaxial apparatus with local measurement of vertical and lateral strains. Results obtained were used to calibrate 8-parameter von Wolffersdorff model. Subsequently, the behaviour of loose and dense sandy samples subjected to different stress paths was predicted.

Opis:
In this paper parameters of the Johnson-Cook (J-C) constitutive material model were predicted more accurately based on the static and dynamic material tests and mathematical modelling of relevant response surfaces using specially developed Matlab scripts. Experimental tests were performed under strain rates of 10-3 and 101 1/s and the temperature ranging from the ambient up to 700°C. As a result, a set of mathematical models which fit the experimental data was determined. The experimentally-derived constitutive models were implemented into FEM-based simulations of real machining processes of Inconel 718.

Opis:
An algorithm for solving the inverse problem of subsurface radiolocation using data from ground penetrating radar is presented in this paper. Experimental research was carried out using the geophysical device "Loza B" in field conditions; a part of airfield runway, located on the territory of Almaty region (Kazakhstan), was investigated. The conclusion concerning the reasons of occurrence of defects on the surface of the runway is given.

Opis:
In the paper the problem of the cast iron substitute thermal capacity estimation is discussed. This parameter appears when the macroscopic mathematical model of alloys solidification bases on the one domain method (fixed domain approach). In the case of cast iron the form of function describing the course of temperature-dependent thermal capacity is quite complex. Using the experimental data, in particular the measured cooling, heating curves at the set of points selected in the casting – mould domain the identification problem has been solved using the gradient methods. The results presented concern the gray iron 3.21% C and 1.9% Si.

An application of parallel computation capabilities in the MATLAB language for the analysis of experimental data concerning the heat transfer coefficient on ribbed walls is presented in this paper. A description of the experimental study, mathematical model and numerical implementation is also given. The obtained results of measurements and calculations shown here clearly indicate the influence of ribbed walls on the heat transfer coefficient distribution in an internal, subsonic flow.

Opis:
The results of experimental and numerical analysis of the influence of the non-axisymmetric pulse shaper position on recorded wave signals in the split Hopkinson pressure bar experiment are presented. The paper focuses attention on the problem of wave signal disturbances caused by a bending wave resulting from non-axisymmetric pulse shaper positions and, moreover, different shaper thickness, striker impact velocities and Wheatstone bridge configurations. The obtained results of analyses indicate that the effect of the non-axisymmetric pulse shaper position may be neglected if deviation from the bar axis does not exceed 20%.

Opis:
The aim of this paper is to compare pre-failure deformations of sand, obtained from a Cam-clay type elastic-plastic model, with experimental data. The experiments were performed in a modern triaxial apparatus, enabling local measurement of both vertical and lateral strains. The experimental programme is briefly described, then a slightly modified, Cam-clay type, elastic-plastic model of sand is presented. Predictions of this model, for different stress paths, are compared with respective experimental results, then extensive discussion of basic problems connected with elasto-plastic modelling of sand is presented. The aim of the discussion is to display some shortcomings of this type of modelling.
