The analytical result is shown as Figure 5, the bucking factor f=3.57>1, so it will not be bucking.

The technique to asses and optimize the chosen factors to attain minimum surface roughness by integration response table and response graph, normal probability plot, interaction graphs, and analysis of variance (ANOVA) technique Palanikumar et al. [5].
They reported that, the material behaviour is not only inhomogeneous, but also dependent on fiber and matrix properties, and type of weave.
The material specification fiber, resin, TiO2 and mechanical properties of composites used in this work are given in Table 1 and Table 2.
The study of surface roughness characteristics of GFRP composites dependent on many factors, it is more influenced by the cutting parameters like cutting speed, feed, depth of cut, etc., for a given machine tool and work piece set-up.
The behavior of composites is heterogeneous and depends on the fiber and matrix properties, orientation of fibers, bond strength between fiber and matrix, and the type of weave.

With model preferences, material properties and boundary conditions are defined, and fluid-solid coupling is calculated.
The parameters, such as the stress and displacement tolerances and relaxation factors, convergence criteria, etc. which control the convergence of the coupled system are determined in the fluid model.
It means that rock creep is the primary factor for steel casing damage, and casing damage is also affected by temperature load or steam injection.
Also this is based on the porosity and permeability of material property.
Beside rock creep, temperature load also affects steel casing damage.

To answer the market demand, process costs reduction and development of new materials with improved properties, constitutes key factors to increase the diffusion of the AM technologies.
Powder Manufacturing Process Optimization Powder characteristics have a strong impact on the processability in the AM machines, influencing the final quality of the component, affecting the powder bed formation and hence the development of melt pools and microscopic homogeneity.
The main powder parameters are: shape, size distribution, density, flowability, porosity, thermal properties, surface properties, impurities.
These properties were studied by variation of Tpouring to evaluate their effect.
The dispersion of ceramic particles allows to improve mechanical properties of metal alloys.

Corrosion morphology image is one of the most important features to evaluate corrosiveness of aluminum alloy, it adversely affects the security and integrity of the aircraft structure [1, 2].
Currently, no studies are found about the corrosive characteristics and mechanical properties for the shot peening aluminum alloy corrosion.
Its mechanical properties are as follows: tensile strength is 510MPa, yield strength is 441MPa, elongation rate is 8% and Young’s modulus of elasticity is 71.7GPa.

In addition, it can also seen from Fig.3, stress distribution is affected by the relative position of pits obviously.

This characteristic, together with its cost and its wide range of mechanical properties, make it an ideal material for industrial functions.
These include S275 structural steel, which has a low carbon content and is widely used for its mechanical properties.
The material employed is a low carbon structural steel (Table 1) widely used in several industrial sectors due to its excellent mechanical properties such as a yield strength of 275 N/mm2, being the carbon steel with the highest yield strength among the most common ones [17].

Through the purification of hydrogen peroxide, the alcohol affecting the performance of concrete in the ethyl acrylate is removed, and then by the experiment of the basic properties, we realize the impurities and the dosage how to influence the properties of the cement matrix.
By using self-reaction ethyl acrylate polymer, adding hydrogen peroxide to achieve the purpose of purification and carrying on a series of modified cement experiments, we expect the purified products to improve the mechanical strength properties of the mortar, and promote the workability, durability, and other basic properties of the cement matrix.
By changing temperature, reaction time, the dosage of the catalyst and other experiment plans, we try to find the best experimental factors.
The main purpose of the experiment is to explore if ethyl acrylate, purified by hydrogen peroxide and then stirred to modified mortar, has any modified impact on mechanical property.

But most of these achievements are carried out only considering a certain single factor.
However, practical concrete structures always subject to the combined action of mechanical load and environmental and climatic factors inevitably.
In recent years, many scholars have carried out researches about durability problems of concrete structures under combined actions of mechanical loads and environmental factors in concrete scientific field [5,6].
