Nacreous coatings on orthopedic implants can be advantageous because of its robust mechanical properties, high biocompatibility, and ability to promote bone growth.
Nacre exhibits comparable mechanical properties to that of natural human bone [3].
Therefore slower coating growth on the Ti implants in this study may have been affected by factors such as diet and animal species.
These factors should be further investigated.

Combinations of working and heat treatment alter the microstructure and change the mechanical properties of the metal.
The microstructure and properties can also be affected by adding other elements to titanium.
Mechanical and thermal properties of the cutting tool substrate.
However, to facilitate the data collection, only four dominant factors were considered in the planning of experimentation.
This is partly due to the complex interaction between various physical factors that control delamination: the intrinsic properties of the coating, the tool and those of the interaction between the substrate, the coating and the workpiece.

The microplasticity determines various properties of the metals, such as fatigue strength, dimensional stability, and various relaxation phenomena, such as internal damping (internal friction) behavior.
Total internal damping affects a number of different, interacting and functioning factors, such as defects in the crystal structure, the movement of dislocations, plastic deformation, grain boundary sliding, elastodynamic and magnetoelastic phenomena.
Mechanical properties of pure magnesium are low.
Therefore, the entity lies in resolving the contradiction between damping capacity and mechanical properties and to create magnesium based alloys which have high damping capacity and sufficient mechanical properties [9,10].

Therefore, it can be concluded that the wear resistance depends on the mechanical properties and the structure of the wood. 3.

Our previous study [1] revealed that CaTiO3 film (K~160, tan δ ~0.003+=0.0003 and TCK~ -1340 ppm/℃ at 6 GHz) and MgTiO3 film (K~ 16, tan δ~ 0.0008+=0.0001, TCK~ +260 ppm/℃ at 6 GHz) exhibited the quite different microwave dielectric properties.
Thermal stress can lead to mechanical (structural) as well as to functional (electrical or optical) failures [4], and this stress is a very significant factor affecting the dielectric properties of materials.
It was reported that the dielectric properties were affected by thermal stress in the interface between the film and the substrate [6].
In this study, the dielectric properties of (300-X) nm MgTiO3/(X) nm CaTiO3 thin films have been investigated with correlation between interface and stress induced by dielectric layers with heattreatment.
The microwave dielectric properties were measured using a circular-patch capacitor geometry with a network analyzer (HP873Es, Aligent) [8].

Dynamic Properties of Long-span Steel-concrete Composite Bridges with External Tendons Wei’an Wanga, Qiao Lib ,Canhui Zhaoc and Weilin Zhuangd School of Civil Engineering, Southwest Jiaotong University, Chengdu 610031, China a vten1@163.com, b ql3721@163.com, c zch2887@163.com, d wlzhuang@vip.163.com Keywords: Steel-concrete composite bridge, Equivalent damping, Shear connectors, Dynamic property, External prestress.
The dynamic performance of large-span steel-concrete composite bridges with external tendons is investigated by deriving the formula of equivalent damping ratios of composite bridges, and by considering the influence of shear connectors stiffness of composite girders, external tendons, and pile-soil dynamic interactions on the dynamic properties of steel-concrete composite bridge.
As steel-concrete composite bridges are made from two materials that differ in their mechanical properties, the structural dampening parameters not only affect the structural dynamic energy dissipation but also closely relate to the structural response[1].
In this study, considering a long-span steel-concrete composite bridge, equivalent damper of composite structure was derived, a refined finite element model of the full bridge was constructed, and the influence of above factors on the dynamic properties of the composite bridge was analyzed.
Equivalent damping Damping is an important structural property that affects the structural dynamic response in both elastic and elastic-plastic phases, so the selection of damping parameters directly affects structural design.

Mechanical Property Characterization.
In terms of fiber testing, the results showed that treating the fibers leads to significant changes to their physical and mechanical properties.
As for the mechanical properties, it can be concluded that treated fibers can withstand more stress, stretch even more, and therefore is more elastic compared to the untreated fibers.

Accordingly, the last decade has seen a tremendous interest in enhancing the mechanical properties of DP steels using micromechanical simulations of Representative Volume Element (RVE).
