Nieustanny rozwój technologii komputerowej i obserwowany wzrost mocy obliczeniowej komputerów otwiera przed inżynierami nowe obszary komputerowej aktywności naukowej. Wirtualną rzeczywistość można skutecznie przystosować do procesów kształcenia i podnoszenia kwalifikacji. Celom tym ma służyć niżej opisana koncepcja wirtualnego laboratorium inżynierii materiałowej. Mimo znacznych problemów z jej opracowaniem, jest to rozwiązanie przyszłościowe dla ośrodków o ograniczonych zasobach sprzętowych. Jako przykład przedstawiono wybrane symulacje rzeczywistego sprzętu badawczego użytego do prowadzenia badań materiałów polimerowych i kompozytowych.

Continuous development of computer technology and the observed increase in computing power opens forengineers’ new areas of scientific activity. Virtual reality can be successfully adapted to education processes of education and upgrading of skills. For these purposes described below material science virtual laboratory concept was developed. Despite significant problems with its development, it is a future-oriented solution for centres with limited hardware resources. As an example, selected simulations of the real research equipment used for testing of polymeric materials and composites materials are presented.

Purpose: Article describe an idea, bases and construction procedures of Material Science Virtual Laboratory. Design/methodology/approach: As an example of virtual laboratory post a virtual light microscope used in metallographic investigations is presented. It allows to study the microstructures from different materials and alloys without use of real microscope placed in real laboratory. The only necessary equipment is the computer with internet connection. Findings: Continuous progress in computer technology and observed growth of computational power opens for material engineers new ground of computer scientific activities with use of virtual reality and computer technologies. Research limitations/implications: The virtual laboratory, even the best programmed, will never be better than the modest real laboratory, but it is good for training and as introduction to further investigations on a real equipment in real laboratory. Practical implications: Virtual reality can be efficiently applied to processes of education, increasing of qualifications and for basics, predefined experiments. Originality/value: In spite of considerable creation difficulties, virtual laboratory is a future solution for environments with limited apparatus supplies.

Purpose: This paper presents ideas and construction kinds of distance learning system based on course management system for distance learning and Computer Aided Teaching in the field of material science. Design/methodology/approach: Paper describes contain and composition of the system including virtual courses and didactic materials for lectures in the discipline of materials science and instructions for classes guided in scientific laboratories used as a supplement for traditional learning methods. \ Findings: This study shows advantages, possibilities and features of already created and introduced e-learning system as a modern tool for distance education and interactive communication with students and between students. It’s also used for publishing of scientific researches and other staff of the Institute. Practical implications: As an example of such system is presented an educational platform applied in Institute of Engineering Materials and Biomaterials at Silesian University of Technology, Mechanical Engineering Faculty, Gliwice, Poland, with use of the “MOODLE” software in October 2004. Originality/value: Article is valuable for persons and institutions, which are concerned with e-learning and distance education, as well for students and all users of such systems.

Purpose: The aim of this paper is the presentation of developed computational model build with use of artificial neural networks. This model describes the influence of PVD and CVD coatings properties on the cutting edge durability from sialon tool ceramics covered with these layers. Design/methodology/approach: Obtained model has the ability to compute the durability of the PVD and CVD coatings coated on sialon tool ceramics blades determined in technological cutting trials of grey cast iron, basing on PVD and CVD coatings microhardness, thickness, grain size and their adhesion to the substrate. Findings: Results of researches, performed with use of computational model, revealed, that the greatest influence on the durability of coated sialon tool ceramics blades have the adhesion to the substrate. Smaller influence on blades durability has the size of grains. Minor influence on the cutting tool from other properties was obtained. Practical implications: Achieved results indicates, that the best coating’s adhesion to the substrate for coating material selection and design of PVD and VD coatings deposition process should have priority in implementation. Originality/value: Obtainment and utilisation of computational model builded with use of artificial intelligence methods
