Moreover, the effect of dissimilar materials and heat treatments on fatigue strength is explored.
Due to the difference in gear materials and heat treatment methods, the equivalent pitting load computed by multi-level design loading approach is not proportional to the gear ratio of each gear.

Delamination is a known mode of failure for composite materials.
In laminated materials, repeated cyclic stresses or impact loads can cause layers to separate, with significant loss of mechanical strength.
Early and reliable detection of such defects is essential for utilization of full potential of these materials.

Effect of Different Packaging Films on Senescence of Kiwifruit Kai Gao1,a,#, Huanhuan Chen2,b,#, Haidong Liu3,c, Chongxiao Shao4,d, Hongyuan Ma2,e,Xinhong Huang2,f,Yanfang Pan2,g 1National Engineering and Technology Research Center of Agricultural Products Freshness Protection, Tianjin, 300384, China 2Key Laboratory of Food Nutrition & Safety (Tianjin University of Science & Technology), Ministry of Education, 300457, China 3Tianjin Gasin-Donghui Preservation Technologies Co., Ltd.
Introduction Kiwifruit(Actinidia deliciosa) is a kind of fruit which has thin skin and much juice ,so it is easy to become soften and dehydration[1].Films can be defined as a simple and effective modified atmosphere form by depending on the respiration rate of kiwifruit and permeability of film or storage structure surrounding products.[2] The objective of this study was to determine the effect of different packaging films during. storage life of kiwifruit Material and method Materials.Kiwifruits(Zhonghua)were harvested freshly from Zibo of Shandong province,China and were transferred to the laboratory immediately.

The hammer rod material is regarded as isotropic material, density uniformity and completely elastomer.
The maximum yield stress is 206.2MPa, less than yield strength and tensile strength of the rod material, but it becomes a dangerous section easily appearing crack because of the asymmetrical alternating stress function.
