The fatigue damage characteristics of an asphalt mixture were analyzed, a new fatigue damage model was constructed based on the Schapery pseudovariable theory and continuum damage mechanics. According to the Schapery theory ...
In this study, the analysis of fatigue fracture of composite plates with an elliptical hole having a longer axis parallel to the direction of the applied force is performed. The plates were made of glass/epoxy preimpregnate ...
We have determined theoretical notch coefficients
with use of the fictitious radius in tubetube
and flange-tube welds. The parameter of
normal and shear strain energy density in critical
planes is applied for estimation ...
The objective of this study is to predict fatigue
life of metal welded boxes. Experimental results
of fatigue life are satisfactory predicted using
an analytical scheme based on the
volumetric approach.
S — N curve of austempered ductile iron was obtained in the range of lifetime including low cycle fatigue domain and high cycle fatigue domain up to 108 cycles. Ultimate tensile strength is used as a limiting value of the ...
На основании обобщения результатов многочисленных экспериментальных исследований предложены и обоснованы эмпирические соотношения между пределами выносливости сталей и
