Then the maximum first principal elastic strain was used as the fatigue damage parameter, which is substituted in the chloroprene rubber's fatigue life equation, to predict the fatigue life of an elastomeric pad in the number of cycles at different compressive loads. The results were compared ...
Crack growth equation: Paris power law Another method to estimate the fatigue life relies on the crack growth rate da/dN, which represents how much a crack grows in every cycle. “da” and “dN” represent the changes in crack length and number of cycles, respectively. (5.3)dadN=cΔkndN...
The fatigue life of a rubber mount was predicted by combining test of material properties and finite element analysis (FEA). The natural rubber material material’s fatigue life equation was acquired based on uniaxial tensile test and fatigue life tests of the natural rubber. The strain ...
Based on the world-wide researches,the reasonable and feasible testing conditions of direct tension for asphalt mixture included specimen dimension,judgment,controlled mode,load frequency and test temperature are determinated. With the fatigue test results by various strain level,equation of strain-life ...

Mechanical performance of additively manufactured (AM) Ti6Al4V scaffolds has mostly been studied in uniaxial compression. However, in real-life applications, more complex load conditions occur. To address this, a novel sample geometry was designed, teste
The load life exponent p and Hertz stress life exponent n increase in the presence of compressive residual stress, which yields increased life, particularly at lower stress levels. The Zaretsky life equation is described and is shown to predict longer bearing lives and greater load and stress ...

Therefore, the sample endurance limit must be corrected to include the effect of the aforementioned conditions on the endurance limit of the part (Se), which can be done using the Marin equation [13], similar to what is done in the analysis of metallic parts (10.15)Se=∏i=1nkiSe′ ...
