It was suggested that the large scattering of the indentation fracture toughness reported by the round-robin tests such as VAMAS was not originated from these factors.
Although the plausible excuse for the origins of scattering among several laboratories was considered as interobserver error in reading the crack length, there have been a few systematic studies about other experimental factors affecting the toughness[4].
Consequently, the calculated fracture toughness was not affected by the elapsed time.
In the model of Lawn et al, the strain in the plastic zone Table 1 Mechanical properties of the Si3N4 ceramics for ball bearings *The data was obtained by the SEPB method.
From these results, it is concluded that those factors was unlikely to be the cause of errors in the fracture toughness by IF technique.

In order to ensure the perfect electrical conduction and acceptable mechanical properties, the assembly has to fulfill some drastic holding force criteria.
This outfit is directly dependent on the indentation depth at the end of crimping, on the materials properties and on the geometrical dimensions.
Geometries and mechanical fields are obtained and then exported in the mechanical holding model to ensure realistic prediction.

Milling Force Modeling and Experimental Research of 300M Ultra High Strength Steel Zhang Huiping1a, Wang Chongxun1b,Lai Yinan1c,Zheng Wenjuan1d 1College of Mechanical and Power Engineering,Harbin University of Science and Technology,Harbin 150080, China a zhping302@163.com, b64744591@qq.com, c laiyinan@126.com, d1013864774@qq.com Keywords: 300M ultra high strength steel; Milling experiment; Milling force; Modeling and analysis Abstract: 300M ultra high strength steel, a new type of steel with broad prospects for development, has good mechanical properties, and is widely used for manufacture of aircraft landing gear.
Secondly, the influence level of experimental factors is compared by orthogonal experiment.
Milling force in milling process is a key factor to affect the processing efficiency, tool life and surface quality, so the research of 300M ultra high strength steel milling force variation has an extremely important significance.
Common empirical model form of milling forces is exponential formula, such as type 1： (1) Where CF is determined by the machined metal and the cutting condition factors; ap is the depth of cut, n is the spindle speed, f is the feed rate, ae is cut width; b1, b2, b3, b4 are four factors that affect the milling force index.
The experimental parameters and results of single factors experiment are taken into the regression equation to verify the accuracy of the regression equation.

Experimental determination of acoustic properties using a two microphone random excitation technique.

This design method, where the various disciplines affecting the overall performance of the rock drill are separated artificially and optimized respectively, would obtain likely a local optimal solution substitute for the overall optimal solution.
In addition, that in this design there is little or no consideration of uncertainty factors affecting the overall performance of the machine, such as manufacturing technology, material properties, geometry, work load and environmental, or that the change of the design parameters and noise factors is too sensitive, makes the designed multi-functional cutting machine unreliable, or the adopted measure is too conservative to economic.
Its core content is uncertainty analysis that studies the influence of uncertainty factors changes on the product or system performance.

Controlled cooling rate is essential in steel production in order to obtain the desired grades for specific mechanical properties.
The mechanical and metallurgical properties as well as the output of the process depend on the rate of cooling of the steel [1].
In this study Gaussian Process model has been used to estimate the cooling rate of the plate using the data for temporal variation of temperature for the entire cooling process and the generated data representative of the factors affecting the cooling of the plate.
