Using the dynamic thermal analysis equipment, Melo and Radford [6] predicted the visco-elastic properties of the transversely isotropic laminates for the different temperature and frequency ranges and described that the storage moduli were decreased with an increase in the loss factors under the effect of temperatures.
In order to determine the natural frequencies and loss factors under different temperatures, the impulse technique can be utilized.
Hence the properties like the loss factor, natural frequency, storage modulus of glass fiber do not get changed during the above temperature range.
It is due to the lower in plane properties of the FRP skins at this orientation.

These cracks highlight the random behaviour of different bricks as a function of several factors, such as the strength of the concrete, the water-cement ratio, the compactness, and the quality of the mixing, hence the need to propose better formulations to take effective account of these limiting factors.

Then, the affecting factors of gully erosion were discussed.
According to the mechanical equilibrium conditions, when the shearing force of driving debris flow motion equal to the kinetic resistance of debris flow, the erodible sediment on the gully bed should be in the critical state, so that Tq=Tz.
Then we can obtain calculation formula of the maximum erosion depth of gully bed: (6) From the Eq.6, we can deduce that the maximum erosion depth is dominated by properties of debris flow (γc or Cv1), scale of debris flow (h1), gully slope angle (θ) and properties of the erodible gully bed (C and φ).

In grinding hardening process, grinding zone temperature directly affects the quality of surface layer of heat treatment.
Therefore, how to take the initiative to effectively use thermal and mechanical action directly on the workpiece in the grinding surface quenching, grinding hardening, as mechanical engineering experts and scholars at home and abroad focus on the technology key of one of the research problem[1,2,3,4].Grinding hardening processing is not only a complex mechanical system, the composite force and thermal process, are also processed material surface microstructure and mechanical properties change significantly.
But, in the actual grinding hardening process, the workpiece surface hardening effect will be influenced by many factors and unstable.
In the automatic temperature control system in the grinding zone, high temperature heat pipe's start-up performance is one of the important factors, affect the heat coming out of the system in consideration of the high temperature heat pipe evaporation, condensation and heat insulation, the length of the proportion of high temperature heat pipe can start is not affected by frozen startup limit [10].

However, in order to improve the properties and eliminate material discontinuous, it is necessary to conduct the remelting process.
The paper presents the remelting processes of thermal spraying coatings in relation to technologies, properties and applications.
Introduction In the case of growing competition on the market, the production of coatings with given mechanical properties is an indispensable part of modern production systems.
The coatings obtained in this way are characterized by specific mechanical properties and adhesion.
These are generally mechanical properties, such as lower strength and modulus, higher strain tolerance, and lower thermal and electrical conductivity.

The welding properties of nodular cast iron are mainly influenced by the carbon content.
The number, dimension and distribution of the graphite nodules, the chemical composition of the matrix (i.e. the Si content) and the morphology of the structural phases are additional factors that could influence the mechanical properties.
The heat and the relatively high cooling speed generated during welding [8] could favor the formation of fragile phases (such as cementite), thus affecting the static and dynamic as well as the machining properties.
The ultimate tensile strength of 380...405 N/mm2 represents only 86...91 % of the cast iron strength and the variation of the friction welding parameters dis not lead to any significant improvements of the mechanical properties
In addition, the austenitization temperature can be reached, thus leading to carbon dissolution and the generation of a carburized layer on a narrow in the low alloyed steel It was observed that the deformation of the graphite nodules during the welding process leads to a reduction of the bearing section of the welded structure, thus leading to a reduction of the mechanical properties.
