Evaluation of the long-term strength of structural materials with random loading
- 14 Downloads
Basic assumptions about the kinetic strength conception of solids and reliability theory methods make it possible to obtain a mechanism for evaluating long-term strength with random operation of an external load.
It was shown from specific experimental data for the long-term strength of wood over a service life of 50 years that with random loading life may be reduced by 32% in comparison with that for constant loading.
