Optimal maintenance policy for a system subject to damage in a discrete time process
Maintenance Cumulative damage Expected cost rate Operation period Renewal reward theory
2012/4/15
Consider a system operating over n discrete time periods (n=1, 2, …). Each operation period causes a random amount of damage to the system which accumulates over time periods. The system fails when th...
An analytical formulation for the fatigue damage skewness relating to a narrowband process
Fatigue damage Uncertainty Skewness Narrowband process Linear oscillator
2012/4/26
In spectral fatigue analysis, the expected fatigue damage is customarily used to ascertain the design fatigue life. The uncertainty of the damage induced by the underlying stochastic process is typica...
Investigation into the nonlinear damage model of coal containing gas
Nonlinear Damage model Coal containing gas Outburst of coal and gas
2012/4/12
By taking the nonlinear deformation properties of coal into consideration, the nonlinear constitutive equation was founded. And in view of the compressible property of gas, the idea of compressive ene...
Changing regularity of rock damage variable and resistivity under loading condition
Rock damage Resistivity Relation equation Acoustic emission
2012/3/28
In this paper, the stress–strain, resistivity and acoustic emission simultaneous test of compression test for rock have been carried out to obtain the regression equation between the resistivity, and ...
