The Theorem of the Resistance of Hydraulic Machine's Materials to Cavitation Erosion and Abrasion

Wang Biao,Wang Yudong,Zhang Zihua,Ye Xianguo

Strategic Study of CAE 2003, Volume 5, Issue 7, Pages 58-61

Abstract:

In order to confirm the dependence of the resistance of cavitation erosion and abrasion (CEA) on the common properties of materials, four typical materials (WC coating, NiCr alloy coating, boron stainless steel and titanium) were used to do the experiments of CEA and cavitation erosion (CE), to do corrosive experiment, and to test their hardnesses. The experiments results indicated that all resistance to CEA and resistance to CE depend on the hardness and the corrosive resistance of materials. The high hardness is the first factor of good resistance to CEA, strong corrosive resistance is the second factor. Meanwhile, the strong corrosive resistance is the first factor of good resistance to CE, high hardness is the second factor.

Some remarks on the engineering application of the fatigue crack growth approach under nonzero mean loads

Jorge Alberto Rodriguez DURAN,Ronney Mancebo BOLOY,Rafael Raider LEONI

Frontiers of Mechanical Engineering 2015, Volume 10, Issue 3, Pages 255-262 doi: 10.1007/s11465-015-0342-1

Abstract:

The well-known fatigue crack growth (FCG) curves are two-parameter dependents. The range of the stress intensity factor ?K and the load ratio R are the parameters normally used for describing these curves. For engineering purposes, the mathematical representation of these curves should be integrated between the initial and final crack sizes in order to obtain the safety factors for stresses and life. First of all, it is necessary to reduce the dependence of the FCG curves to only one parameter. ?K is almost always selected and, in these conditions, considered as the crack driving force. Using experimental data from literature, the present paper shows how to perform multiple regression analyses using the traditional Walker approach and the more recent unified approach. The correlations so obtained are graphically analyzed in three dimensions. Numerical examples of crack growth analysis for cracks growing under nominal stresses of constant amplitude in smooth and notched geometries are performed, assuming an identical material component as that of the available experimental data. The resulting curves of crack size versus number of cycles (a vs. N) are then compared. The two models give approximately the same (a vs. N) curves in both geometries. Differences between the behaviors of the (avs. N) curves in smooth and notched geometries are highlighted, and the reasons for these particular behaviors are discussed.
