Application of the first-passage time method to tribological problems

  title={Application of the first-passage time method to tribological problems},
  author={V. V. Ryazanov},
All real physical (tribological) processes occur with changes in entropy. We assume that the first-passage time is equal to the time to failure. Method the first-passage time can be effective in tribological problems. The time until the failure of some node of the system or until the end of some stage of the operation of the tribological system is associated with the change in entropy in the system that occurs during this time. Methods of the first-passage time by a random process of some given… 



First-passage time and change of entropy

The first-passage time is proposed as an independent thermodynamic parameter of the statistical distribution that generalizes the Gibbs distribution. The theory does not include the determination of

Entropy in Tribology: in the Search for Applications

The objective of this paper is to answer the frequently asked question “is there any practical application of the thermodynamics in the study of friction and wear?” and to show that the thermodynamic methods have potential for both fundamental study ofriction and wear and for the development of new materials.

First passage times of mesoscopic charge transport and entropy change

The first-passage-time statistics of a stochastic process N(t) for electrons transferred through a metallic double dot are considered. It is shown that in calculating the average of the first-passage

First passage time distribution in heterogeneity controlled kinetics: going beyond the mean first passage time

This work derives rigorously the complete distribution of first passage times (FPTs) for a simple heterogeneous system and reveals a previously overlooked third characteristic time scale of the first passage dynamics mirroring brief excursion away from the target.

Lifetime distributions in the methods of non-equilibrium statistical operator and superstatistics

AbstractA family of non-equilibrium statistical operators is introduced which differ by the system age distribution over which the quasi-equilibrium (relevant) distribution is averaged. To describe

First-passage time: a conception leading to superstatistics

To describe the nonequilibrium states of a system we introduce a new thermodynamic parameter – the lifetime (the first passage time) of a system. The statistical distributions that can be obtained

Statistics of Infima and Stopping Times of Entropy Production and Applications to Active Molecular Processes

We study the statistics of infima, stopping times and passage probabilities of entropy production in nonequilibrium steady states, and show that they are universal. We consider two examples of

We consider the problem of estimating the mean entropy production rate in a nonequilibrium process from the measurements of first-passage quantities associated with a single current. For

An Entropy Based Low-Cycle Fatigue Life Prediction Model for Solder Materials

A new entropy increment model is developed based on the frame work of continuum damage mechanics to determine the entropy increment during the fatigue damage process and the theoretical predictions show good agreement with the experimental data.
