A model for creep life prediction of thin tube using strain energy density as a function of stress triaxiality

Tahir MAHMOOD, Sangarapillai KANAPATHIPILLAI, Mahiuddin CHOWDHURY

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 2,   Pages 181-186 doi: 10.1007/s11465-013-0257-7

Abstract: The model employs strain energy density and assumes that the uniaxial strain energy density of a componentcan be easily calculated and can be converted to multi-axial strain energy density by multiplying itto a function of stress trixiality which is a ratio of mean stress to equivalent stress.and elastic-plastic-creep finite element analysis (FEA) is performed to get multi-axial strain energy densityof the component which is compared with the calculated strain energy density for both cases.

Strategic Study of CAE 2004, Volume 6, Issue 8,   Pages 28-34

Abstract:

The distribution function is an important tool for the study of the stochastic variances.The normal distribution is very popular in the nature and human society.While the fuzzy theory is widely used, the completely certain membership function which has no any fuzzinessThe normal cloud models not only broaden the formation conditions of the normal distribution but alsomake the normal membership function be the expectation of the random membership degree.
