The curves are constructed with new relations Scale, for manufacturing blades and runners for hydraulic turbines. There are presentedĭiagrams in which the four mentioned resistance categories are confined through the curves 1/MDER(), 1/MDER(1), 1/MDER() and 1/MDER (1) were is a parameter grouping the principal mechanical properties and Ĭontains supplementary the influence of the structural constituents the same parameters having the index 1 areĭimensionless ones, obtained by splitting with the values of the standard steel OH12NDL used in the past, on a large There haveīeen used laboratory results for 17 stainless steels having various structural constituents. Yield limit and Brinell hardness) and the rate between the chromium and nickel equivalents (Cre/Nie). This value is correlated with the principal mechanical properties (ultimate resistance, As defining parameter of the cavitation erosion resistance was chosen the value 1/MDER (the inverse ratio The classification used the four classes (super resistant,Įxcellent, very good, and good resistance), established previously for the same steels tested in the old T1 facility with Recommendations of the ASTM G32-10 ASME Standard. Timisoara Polytechnic University (UPT), based on piezoelectric crystals. From this purpose was used the T2 laboratory vibratory facility, realized in the Cavitation Laboratory of Paper presents a method for classifying the stainless steels from the point of view of cavitation erosion
On the basis of theseĪnalyses, the geometry prediction to the required eigenfrequency of the structure is enabled. Translations and design as causer of change in the main features of big and responsible structures.
This is a topic which talks about linear and nonlinear analyses, small and large structure The paper also discovers – computes, what is gained by fastening a high tower to a building On the basis of these analyses, a disposition area The FEM technology in the form of more successive discrete analyses. The research was performed numerically using This paper considers the influence of geometry choice, actually the height choice to the change of own staticĪnd dynamic parameters of a heavy frame structure like tower crane. Transient Thermoelastic Analysis of Dry Clutch System Experimental Web based tools, called Genetic and BacterialĪlgorithm Calculators, are briefly described and their implementations are shown and explained. Relations to engineering calculations is discussed. The implementation of the contemporary Web technologies for the preparation of realistic Web visualizations and their The innovators have to know (predict) what is awaiting them (the result) after crossing theīorder between the routine and innovative area. It is underlined that the ability to make predictions (mainly based on engineering calculations) is very important for the To the problem of overcoming the gap between the Web based mathematical calculations and the realization of Simulation for assuring such E-learning and functional environment for the needs of open innovation. The aim of this research is to combine the computational intelligent techniques with the web based modeling and Innovators have to be informed about the possibilities to undertake creative actions, to be provoked to do them and toīe supplied with a suitable user-friendly environment. It is obvious that the innovation is based on challenging existing assumptions and ways of thinking and that the Text, figures, tables and etc., without using the deep knowledge that the documents can provide for direct modeling and Mainly the students/engineers search and refer to many electronic documents, which include Unfortunately, contemporary Web technologies are not used rationally in the engineeringĮducation and practice.
Nowadays the Internet has become the most powerful and the cheapest communication tool for the people
