The crack not only affects the casting process but will also affect the smooth anterograde slab quality.
In continuous casting process, molten steel solidified shell subjected to hydrostatic pressure, bending, impact resilience and straightening and other factors, when the force exceeds the slab temperature ultimate strength and ultimate strain, it is easy to crack; When the resultant force is less than the limit of the material under high temperature performance to ensure the continuity of the solidification, effectively prevent the slab surface and internal cracks [2].
Lots of studies show that steel mechanical properties (strength thermoplastic and heat) is of the most important indicators of the impact of crack formation in the casting temperature range [3].

Introduction The aluminum bronze alloys are a family of alloys of copper which provides a combination of mechanical and chemical properties unequaled by any number of other alloys.
The great difficulty is to obtain a reliable safety factor without affecting the weight and value of the final product.
The screws of turbine blades, which are constantly subjected to high temperatures, have parts made of material which allows the coping not only the effect of heat but also the cavitation erosion, one of the factors responsible for corrosion.
The choice of track to be used for the machining parameters during the execution of the work depends on several factors, including: the type of material to be machined, the machine available for work and the cutting tool selected.

After main influence factors of structure failure are analyzed by analytic hierarchy process and fuzzy clustering analytical method, it’s necessary to quantitatively analyse the importance of these factors’ influence on reliability furtherly.
The first, as to one certain output variable, which are the most important input variables affecting output result.
Therefore, in order to study effects of all the factors on structural failure, it’s enough to study the effects of mean and mean square deviation [7] .
In order to study the influence of these indefinite factors on reliability indices, it’s necessary to combined the finite element method with ansys PDS technique.
The conclusion is identical with mechanical properties, and the result of the sensitivity pie chart is in accordance with analytic hierarchy process, which verify the accuracy of the above method.

Because modulus of elasticity is sensitive to changes in material structure, they can also be used for prediction strength of concrete and mortars as well for evaluating inhomogeneity or changes in their physical and mechanical properties. [1].
The formula for calculation Ecu, the longitudinal dynamic modulus of elasticity in MPa, described by using UPVM is defined as: Ecu=ρ∙vL2∙1k2 (1) Where ρ is the density of concrete in kg∙m-3 vL is the velocity of ultrasonic pulse in km∙s-1 k is the factor of specimen dimensionality For our experiment, we can choose k factor equal to 1, because it has a constant value and it will not affect our comparison.
Because all volunteers measure the same sample, the factors affecting measuring the amount of ultrasonic gel and the pressure they develop on probes, so it affects the thickness of ultrasonic gel layer and how accurately they place the probes opposite each other.
And because this method is widely used, it is appropriate to pay attention to this issue before choosing the most appropriate measuring method, choosing more suitable conditions or to take affecting factors into account when interpreting the results.

Linear Friction Welding, used to weld non-axisymmetric components and Accumulative Roll Bonding, used to increase the mechanical properties of sheet metals, were considered.
This microstructural change alters the mechanical properties.
The obtained joints are characterized by better mechanical properties than those obtained by fusion welding methods.
Accumulative Roll Bonding (ARB) [4], used to increase the mechanical properties sheet metals, was considered as forming process.
As ARB is considered, roll speed greatly affects the strain rate, while roll diameter and distance between the rolls greatly affect the strain (Table 1).

A structure's ductility is influenced by a variety of factors, such as its shape, connections, composition, and structural components.
Governing Concrete Properties to Cause Shear Cracks The concrete characteristics of these structural components significantly influence their behavior, and several key factors contribute to their main defects.
