In view of the problem that special gondola cars are generally insufficient for actual transportation coke, and in order to improve efficiency reduce cost, 80 t depressed-center car coke is designed by anti-fatigue design method this paper. The body with a supporting bar without simulated analyzed finite element method; results show there stress mutations at transition area two key welds, espec...

bstract Solid lubricating coatings comprise a large segment of tribological materials and under a spherical contact the coating/substrate interface xperiences cyclic shear stress that leads to delamination of the coatings from the substrate and premature failure. The polymeric solid lubricating oating used in this study is an expanded PTFE/epoxy composite. The coatings experience cumulative dam...

To evaluate the effectiveness of recovery strategies on physical performance during a 3-day tournament style basketball competition, 29 male players (mean age 19.1 years, s= 2.1; height 1.84 m, s= 0.34; body mass 88.5 kg, s= 14.7) were assigned to one of three treatment groups: carbohydrate+stretching (7.7 g kg(-1) day(-1), s= 1.7; 'n = 9), cold water immersion (11 degrees C, 5 x 1; n = 10) or ...

In this Report factors affecting the accuracy of Miner's Rule are dls-cussed. An nvestlgation 1s also described of the cumulative damage behaviour of DID 5014 alumlnlun alloy lug specuwns using random loading. It 1s concluded that the devlatlons from Miner's Rule observed in the uxestlgation can be ascribed manly to the actlon of residual stresses associated with yielding at tllf point of fatzg...

In the past several years the cyclic nature of Heat Recovery Steam Generators, HRSG’s, has increased dramatically. There are many methods for evaluating cyclic service. Several methods for evaluating cycle life are compared for their use on HRSG’s. A discussion of strengths and weaknesses of each method is presented. INTRODUCTION ASME Section I [1] and Section VIII, Division 1 [2], do not provi...
