Dear All,
I'm performing a fatigue life analysis of some standard specimens. The problem is I always get very small values (less than 1e-5) for the number of load cycles for each step of crack propagation! I used Paris and NASGRO formulas, but quite the same results. The SIF calculations are wroking correctly, since I'm using a commercial code to do that and I did double checked them to see if they are accurate enough. So, only Paris or NASGRO's parameters may bring some errors. But, I got them from the literature, for example: c = 1e-13 and m = 3.2 for Al 7075-T6. It's a simple caculation, don't know what exactly causes the problem!
Any advice would be greatly appreciated,
Mohammad

This video presents our work on a new definition of Life-Time based on Thermodynamics State Index. Where life-span prediction of organic and inorganic systems can be done computationally without phenomenological models.This video was created by Professors Leonid Sosnovskiy,(Laureate of the State Prize of Ukraine, and Honored Scientist of the Republic of Belarus), Sergei Sherbakov (Prof. of Theoretical Mechanics at Belarus State University) and Cemal Basaran (Prof. of Solid Mechanics at University at Buffalo, SUNY) based on the universal phenomenon of thermodynamic state change (degradation) of inorganic and organic physical systems. This video is the result of their work on unification of Mechanics and Thermodynamics. The new unified theory defines a new concept of Life-Time, aimed to define the modern theory of evolution of the universe. Mathematical and experimental proof of the theory is available in publications by the authors and by other researchers in the literature. Mathematical proof of the theory is in Journal Entropy 2016
Elastomers are outstanding in their ability to repeatedly endure large deformations, and they are often applied where fatigue performance is a critical consideration. Because the macromolecular structure of elastomers gives rise to a number of unique behaviors, appropriately specialized methods are needed to characterize, analyze, and design for durability. This 2-day course provides the know-how for engineering durable elastomeric components and systems. The course is taught at Axel Products, and includes live demos of typical behavior.
