The historical plastic deformation and temperature rise will deeply affect the material properties which will be adopted in the next simulate stage, i.e. burr formation.
A coupled thermal-mechanical model of plane-strain orthogonal metal cutting is developed.
Deformation of the workpiece material is treated as rigid-plastic with isotropic strain hardening, and the numerical solution accounts for coupling between plastic deformation and the temperature field, including treatment of temperature-dependent material properties.
In this study, the shear friction factor µ of 0.65 is used.
Similar to other factors (such as friction or flow stress), this value can influence the predictions and must be estimated with reasonable accuracy [10].

These characteristics make nanofibrous layers have different properties in comparison with currently porous fibrous materials[1].
The rheological properties of solutions and the morphology of nanofibers membranes was examined with rheometer (Ar2000, AT, America) and microscopy (S4800, Hitachi, Japan), respectively.
Mechanical properties were measured with a Instron mechanical tester (3365, Instron, America), under a speed of 10 mm/min.
Results and Discussion In the process of spinning, shear rate is one of the important factors that affect spinning liquidity.
The possibility of a movement of nanofibers in structure and inner friction in polymer layer has an impact on the final absorption properties of the material.

Even with laser welding, martensite in the heat-affected zone disintegrated and resulted in a softened, heat-affected zone as compared with the base materials.
The tensile strength of a butt weldment was determined by the strength of the heat-affected zone.
The tensile-shear strength of an overlap weldment was determined by not only the strength of the heat-affected zone but also bead shapes such as blow holes, underfill, and the bead width at the faying surface.
The mechanical and metallurgical properties of the laser welds were analysed.
The bead shape such as the width at the faying surface and underfill was a dominant factor in determining the tensile-shear strength of weldments.

Location of the restoration, the type of support and the design of the restoration were assessed as possible factors influencing chipping rate.
Introduction During the recent years, zirconia-based restorations have gained great popularity. [1,2] These metal-free restorations are considered to offer esthetic biocompatibility, as they contain a zirconia framework that can come in multiple shades to provide a more biomimetic outcome.[3] They offer improved optical properties – the light transmission is better than that of metal-ceramic restorations, which are very opaque.
Several factors have been investigated in laboratory studies, among which: the thermal compatibility of the veneering ceramics and the zirconia frameworks [11], the surface treatment of the framework, the bond strength between the veneering ceramic and the zirconia framework and the flexural strength of the veneering ceramics [12].
Every complication affecting each unit of a restoration was documented as a separate incident.

Introduction The excellent mechanical properties of exotic materials such as titanium alloys, carbon fiber reinforced plastics (CFRP) and metal matrix composites (MMCs) have led to many applications in aerospace and high value added industries.
Water content is also a factor.
The “signal” is the square of the mean value of the results; whereas “noise” is a measure of the variability of the response, it is caused by uncontrollable factors (noise factors).
These results show the significance of each factor, and the rank of contributions each factor made to the results.

The relationship between precipitation behavior of MX(M=V, Nb) nitrides and mechanical property during aging in 7Cr-1.5Mo ferritic heat resistant steels were investigated in this study.
Therefore, it is required to develop the heat resistant alloy with superior high temperature mechanical properties.
The relationship between precipitation behavior of MX(M=V, Nb) nitrides and mechanical property during aging in 7Cr-1.5Mo-VNbN ferritic heat resistant steels were investigated in this study.
During exposure to elevated temperatures and creep stress, pronounced microstructure evolution occurs (recovery, grain and subgrain coarsening, precipitate coarsening), which causes the mechanical properties to deteriorate.
Factors affecting the coarsening rate of MX nitride precipitates are interfacial energy, γ, diffusion coefficient, D , solubility of particle in the matrix, ∞C , and molar volume in the particle, mV , in the case of a constant temperature.

The load bearing capacity of the composite construction is primarily affected by the material properties of the timber beam and the concrete slab.
These building materials are called high performance concerning their fresh concrete properties as well as their hardened concrete properties.
Two main factors are important in this case.
It often requires several different properties of the used concrete.

Introduction The great interest in cellular ceramics has been associated mainly with their specific properties, such as high permeability, high surface area, low mass, low specific heat and low thermal conductivity.
These properties are found to be essential for a set of technological applications such as filters for molten metals and hot gases, refractory linings for furnaces, catalyst supports, and biomaterials implants. [1,2].
This variety of properties is very dependent on processing methods and corresponding conditions [3].
The evaluation of the rheological properties of suspensions and emulsions is an important step in the cellular ceramic development.
In wet processing, the rheological factor can be a limitation to the use of determined raw material as well as the dispersant agent [9].

Being a non-mechanical metal removal process, ECM is capable of machining any electrically conductive materials with high stock removal rates regardless of their mechanical properties, such as hardness, elasticity and brittleness.
These process parameters are capable of affecting the machining accuracy of ECM.
According to ECM electrolyte fluid theory, two main factors, electrolyte temperatureT and electrolyte pressure between electrolyte inlet and outlet P have important influence onκ.
The main causes resulting in high failure rate is that there are so many various ECM process parameters which can affect ECM process stability and machining accuracy.
