3. Contribution and influence of statistical modelling of random stress in the calculation of service life

3.1 Principle of damage calculation

The data, around which theoretical probability density models exist, are of three kinds :

  • amplitudes grouped into classes ;

  • extreme amplitudes ;

  • the solicitation envelope.

  • Three calculation models...
