Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Stress relaxation is a phenomenon which occurs for components subjected to stress and temperature and natural creep is some how arrested. That the natural creep gets arrested due to prevailing constraints is a common experience and stress relaxation is almost always present. This subject of stress relaxation which is of concern in design of high temperature components is the theme of this research. Relaxation is studied next using these creep laws and a relaxation model. Five different relaxation models are considered and uniaxial (pure) relaxation is studied. A typical bolt material (x 22 crMo V 121) is used for analysis. The experimentally observed relaxation is used to evaluate various relaxation models. Larsen Miller parameter (LMP) which is quite commonly used in creep calculations is advantageously used to evaluate self-consistency of various creep laws and the relaxations derived there from. Practical cases of stress relaxation like relaxation under stress gradient and temperature gradient & pre tensioned bolt are studied. Some programs in the form of spread-sheet, Fortran, and ANSYS macros are also developed. 184 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A356 as matrix and nano SiC as reinforcement material nanocomposites are fabricated in this work. Since nanoparticles tend to agglomerate into large clusters during composite processing, effect of ultrasonic cavitation to avoid agglomeration and clustering of nanoparticles in melts is studied. Cavitation pressure required to be developed by the ultrasonic transducer to disperse reinforcements is evaluated. Uniform distribution of nanoparticles is ascertained by SEM test. EDS analysis reveals that there is no contamination of the fabricated composite. Fabricated nanocomposites are then machined into tensile, wear test specimens of dimensions according to ASTM standards. Mechanical properties like tensile strength, hardness, ductility, sliding wear resistance are evaluated and compared with pure aluminum alloy. Machinability and electrical conductivity also evaluated. In the present work, an attempt has been made to confirm the applicability of ANN techniques for prediction of wear of MMNCs by comparing the results of ANN with the experimental results. In addition to the above prediction model, yield strength results are validated using an analytical model. 160 pp. Englisch.…
