Tytuł:: Fatigue "safe-life" criterion for metal elements under multiaxial constant and periodic loads
Autorzy:: Kolenda, J.
Powiązania:: https://bibliotekanauki.pl/articles/259403.pdf
Data publikacji:: 2004
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: design criteria

periodic stress
mean stress effect
Opis:: Periodic stress with Cartesian components given in the form of Fourier series is consideŹred. To account for the mean stress effect the generalised Soderberg criterion for ductile materials is employed. An equivalent stress with synchronous components is defined by means of the equivalence conditions based on the average strain energy of distortion. The fatigue "safe-life" design criterion is formulated which covers the conditions of both static strength and fatigue safety and includes material constants that have simple physical inŹterpretation, can be determined by uniaxial tests, are related directly to the applied loads and can reflect material anisotropy.

Tytuł:: High-cycle fatigue criterion for anisotropic metals under multiaxial constant and periodic loads
Autorzy:: Kolenda, J.
Powiązania:: https://bibliotekanauki.pl/articles/259537.pdf
Data publikacji:: 2005
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: design criteria
multiaxial loading
periodic stress
mean stress effect
Opis:: Periodic stress with Cartesian components given in the form of Fourier series is considered. To account for the mean stress effect the modified Soderberg's formula is employed. An equivalent stress with synchronous components is defined. The design criterion for a finite fatigue life of metal elements is formulated. It covers the conditions of both static strength and fatigue safety in the high-cycle regime and includes material constants which have simple physical interpretation, can be determined by uniaxial tests, are related directly to the applied loads, and can reflect material anisotropy.

Tytuł:: Fatigue "safe-life" criterion for metal elements under multiaxial static and dynamic random loads
Autorzy:: Kolenda, J.
Powiązania:: https://bibliotekanauki.pl/articles/259229.pdf
Data publikacji:: 2004
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: design criteria
multiaxial loading
random stress
mean stress effect
Opis:: Random stress with Cartesian components of known statistical moments of their mean values and power spectral densities of stochastic stress processes is considered. To accoŹunt for the mean stress effect the generalised Soderberg criterion for ductile materials is employed. An equivalent stress with periodic (in the mean-square sense) components is defined by means of the equivalence conditions based on the average strain distortion energy. Also, is formulated the fatigue "safe-life" design criterion which covers the condiŹtions of both static strength and fatigue safety and includes yield strengths and fatigue limits which : have simple physical interpretation, can be determined by uniaxial tests, are directly related to the applied loads, and can reflect material anisotropy.
