Abstract: It is common to assume identical allowable safety factors in static strength [m ], defined by mean stress (S m ), and in fatigue [a ], defined by stress amplitude (S a ), in order to ...

Abstract: The equivalent stress concept allows the comparison of arbitrary multiaxial stress states with a uniaxial one. Based on this concept several limit surfaces were formulated. The trend in the formulation lies in the generalized ...

Abstract: At the location of intermittent turbulent boundary layer separation a finite positive mean surface shear stress still exists. It is demonstrated that viscous coordinates and a mixing length ...

Abstract: Upper bounds on Newton’s, Poisson’s, and energetic coefficients of normal restitution for the frictional impact of rigid pendulum against a fixed surface are derived, demonstrating that the upper ...

Abstract: In the previous publication [2], the transformation between fatigue life and strength distribution was established using double-logarithmic coordinate system (InN-InS). Here, a similar transformation ...

Abstract: A mathematical model for collisions between birds and propellor-type turbine rotors identifies the variables that can be manipulated to reduce the probability that birds will collide with the ...
