The present paper presents experimental results concerning the mechanical characterization of an
optimized cork agglomerate with enhanced mechanical properties.
Mechanical properties of these cork agglomerates were improved by using conventional cork granulates (with different sizes) with an epoxy resin as adhesive element.
Damage mechanisms affecting cork /carbon sandwiches begin with a small shear crack which propagates from the loaded zone following the direction of the middle plane towards the tips of the specimen.
These images allow inferring that PMI foam/carbon sandwiches absorb all the energy resulting from impact, leading to a deep perforation affecting the face sheet and also a considerable extension of damage within the core material.

This had been encouraged by desirable esthetics and translucency, higher mechanical and better biological properties of ceramics.
Dimension of connectors and length of the pontics also have been another critical area affecting the success rates.
The model has been divided into many regions as shown in Fig. 3 and their mechanical properties which based on the previous work is shown in Table 1.
However, this study has some common limitations due to the 2D modeling of FPD structure and its mechanical properties.

But the process of the metal wear is complicated because of the characteristics of the influenced factors[2-5].
The main factors that affect the wear performance are choosed from the point of environmental factors, working conditions and material properties.
The factors include PB value of the lubricant ,which is the main character of the lubricant of resisting wear ;the hardness (H)of materials ,which can represent the surface property of the parts; the load(P) and velocity (v)of the samples, which determine the working condition of the samples.
As there four main factors are considered ,so the prediction modal includes four variables and the wear volume is the dependent variable.
As we know that there is interactive effect between the influencing factors ,so the relation set (Eq.2) is needed in order to establish the function between mean wear volume and the four factors

The resulting microstructure is the foundation for most of the following microstructure
evolution effects occurring during further processing (rolling, extrusion), thus affecting properties of
the final product.
The coarse grain structure is compressed and usually begins to recrystallize and particularly brittle constituent particles brake up into small pieces affecting formability, also of the final product.
With this concept it is now possible to follow the microstructure (grain structure, texture and microchemistry) and associated mechanical properties through the whole process chain from DC-casting to forming.
It now is possible to combine models on various levels for a complete simulation of the process chains which involves microstructure evolution and resulting mechanical properties.

Various parameters including tool geometry, rolling volume,
rolling speed, rolling position, the thickness of blanks and material properties, affect the processing
surface feature, mechanical and physical performance in different degrees.
Rolling technology is a process which plastically deforms the material's geometry and also changes the mechanical properties of the material.
Influence factors and parameter settings.
The most important factors in the rolling process including rolling depth, △h, and rolling position, P, have been discussed.

Abstract: Hollow glass fiber with full of repair agent is embedded in concrete to repair components, and one - third point loading experiment is carried out to test the mechanical properties of it.
In order to obtain a better effect of bridge concrete crack self-healing, the crack width is one of the major factors.
Design and fabrication of specimens The test is about the self - healing and the effect of crack width on the self - healing properties. 12 groups (36 pieces) of 100mm × 100mm × 400mm concrete beam specimens are produced.
The specimen is put back into the box to continue conservation for 5 days, test the mechanical properties until healing is curing agent completely.

Clay brick blocks, which have very different mechanical properties, are commonly used as masonry units for building masonry walls.
Data on the mechanical properties of masonry walls from the materials used in Montenegro are scarce.
According to previous experimental studies, the most significant contributions to the mechanical properties of the masonry wall are given by mechanical properties of masonry units.
