PROCESSING OF LOW-CYCLE FATIGUE TESTS DATA ON A BASE OF KINETIC FATIGUE THEORY

Author SYZRANTSEV V.N., SYZRANTSEVA K.V., ILINYKH V.N.
Source International Journal of Engineering and Applied sciences pp 07- 10 Vol 06. No. 04, 2015
Abstract

To describe the results of tests of samples destruction in a field of low-cycle deforming authors use mathematical model developed in the kinetic theory of mechanical fatigue. Two additional parameters were included in developed model. First parameter characterizes the initial damage of part material, which exists before cyclic deforming of part. Second parameter describes the part resistance against the growth of fatigue cracks. Proposed earlier methods of experimental determination of these parameters values in real operational tests of parts do not allow to obtain required information. The paper considers the task of calculation of these parameters based on results of sample's longevity tests and developed mathematical model. ..

Abstract

The use of fractional calculus when modeling phenomena frequently suggests several questions concerning the deepest parts of the physical laws involved in. Here we will be dealing with one instance of such situation. We will be showing that a very large class of viscoelastic systems are equivalent to a pure viscous (Newtonian) process observed in a discrete time scale.

Abstract

Automotive engine is one of the internal combustion engines in which combustion of mixture (air-fuel) burn internally. It contain different parts which are to relate together to have required engine efficiency. Among these parts is the piston which contains the piston ring that maintains a perfect seal between the cylinder wall and the piston. The dimensional relationship of the piston ring determines the degree by which their seats in the groove of the piston thereby determine the efficiency of the compression of the engine which affects the output of the engine. This paper examines the effect of piston ring radial thickness on the piston ring gap. Visual basic computer code was developed for computation of piston ring radial thickness corresponding to the piston ring gap. ....
