By studying and analyzing the splitting process theory, affecting factors on splitting quality and the expansion force ratio, finite element analysis was conducted by using modern engineering software.
Fig. 3 Connecting rod blank with cracking notch In addition to the applied load size and speed, friction coefficients of the relative movement surfaces and the wedge angle are also important factors for splitting quality.
Affecting Factors on Fracture Splitting Quality.
Affecting factors including connecting rod material, the shape and thickness of cracking notch and fracture cross section, and splitting device and parameters.
Fracture splitting process requires the material to have good mechanical properties to meet the requirement of connecting rod, meanwhile, the toughness index of the material should be limited to avoid large plastic deformation, conducive the realization of brittle fracture and ensure the quality of fracture cross section.

Furthermore, Heat Affected Zone (HAZ) tests are being introduced.
The complex correlations between the factors do not allow defining other properties (e. g. mechanical properties) through characteristics.
This chapter aims to present the properties of HAZ of (Q+T) high strength steel joints by the use of physical simulation, while the effect of welding parameters (t8.5/5 cooling times) on the different HAZ zones is also investigated.
Approaching to the lower limit, the risk of cold cracking increases, in case of long cooling times the reduction of toughness and strength properties can be expected.
- Using the Gleeble 3500 thermo-mechanical physical simulator the critical zones of S960QL HAZ can be reproduced.

The main reason is that the non-uniformed interface between the wafer and the machine-pad adversely affects the polishing performance and ultimate surface uniformity.
Properties of CU.
That is, the CU is the product of two factors.
The first factor to the right of the equal sign measures the within-groups component, that portion of CU attributable to dispersion among group members.
The second factor measures the between-groups component, that portion of CU attributable to differnces in means across groups.

Using Atomic Force Microscopy to Retrieve Nanomechanical Surface Properties of Materials S.
Besides topographical visualisation, many surface properties of materials (e.g. mechanical, tribological, chemical, thermal, electric and magnetic) can be studied by using this tool [2].
In this work, the effect of some of these factors on the accuracy of nanomechanical properties evaluation, by using atomic force microscopy techniques, is analysed.
In this way, other factors must be considered, which will be briefly discussed in the next section.
Material related factors that can affect nanomechanical tests Once instrumentation and measurement errors are minimized, as discussed in the previous sections, the differences between nanomechanical and micromechanical properties (Table 1) must be attributed to material related factors, which are "hidden" in macro and microscale tests but become relevant in tests performed at nanoscales.

Then it has made sensitivity analysis of affecting ground deformation factor by neural network hierarchical analytical approach.
Because there are many factors affecting underground construction ground deformation, and the factors often are combined action.
But it can not roundly reflect the real deformation in the factors combined action.
In view of this, the main goal of the paper is to utilize the current most popular one of artificial intelligence method, artificial neural network principle to forecast multiple factors, which would affect underground engineering construction ground deformation.
Soil physical mechanical property, like modulus of compression, void ratio, moisture content, cohesive force and internal friction angle are all important influence factor for sedimentation, especially for long time concretion and secondary consolidation concretion.

Many papers, therefore, discussed about the mechanical properties for practical uses [2-4].
In addition, it was pointed out by Hojo et al. that the cleaning process of SiC particles, in which the particles are washed in an acidic solusion to remove impurities, affected the particle dispersion into a nickel matrix and thus the mechanical properties [9].
The Stribeck curve gives a reasonable evaluation on frictional properties under a line cotact lubrication [10].
Their friction properties are also discussed

A stochastic analysis of multi-scale problem in honeycomb microstructure was introduced in this paper to determine the variation of macroscopic homogenized properties considering uncertainty of micro-property.
The numerical results showed that even with minor geometrical defect could affect the macroscopic properties.
The macroscopic homogenized properties of porous materials are supposed to be influenced by the variation of geometrical information X and microscopic mechanical properties D, as written in eq. (1).
It is because many uncertainty factors may arise at microscale could influence the dispersion of macroscopic property.

Studies had shown that the comfort of clothing was determined by many factors, such as material, garment structure and wearing state[1].
Experimental The trial was divided into two parts: test of elastic properties and extension properties of knitted fabric, and objective clothing pressure measurement. 1.
The mechanical extension properties of fabrics were measured using a strength tester (YG026B).
The relation between clothing pressure and mechanical properties of fabrics In the Fig 4, the coordinate 1 to 8 on the X-axi means elastic recovery rate on warp direction 80%, 83%, 86%, 89%, 92%, 95%, 98% and 100%.
As all factors, such as environment and clothing construction, were controlled, the variable which was changed was the fiber content of the knitted fiber content.

However, during the repeated recycling processes, degradations occur in mechanical properties [11].
This degradation occurs as a result of heating, processing, and other factors during the recycling processes leading to declines in quality [22,23,24,25].
In addition, colouring, heating, and processing also affected the optical properties of polymers [35].
