| Abstract [eng] |
For determination of lifetime of structural elements number cycles Nc before fatigue crack appearance must be known. Dependence of cyclic plastic strains δ on the number of cycles Nc can be expressed by Coffin`s law. but determining of material cyclic constants C and m for cyclic non – stable materials is complicated because in this case the cyclic plastic strain δ depends on number of cycle N. Therefore an equation was proposed by M. Daunys, which approximately may be used for determination lifetime on the interval of cyclic strains . |
