Such an assembly generates a nontrivial fiber bundle of material manifold.
We introduce material manifold as a fibre bundle of a smooth three-dimensional manifold.
Note that material manifold is a bundle and each its fiber is associated with a material surface strained before its adhesion to a body.
Thus, at each point of the material manifold tensor field is defined.

Therefore, these PE/TiO2 composites with such mechanical properties and bioactivity are considered to be useful as bone-repairing materials.
Introduction Recently, many kinds of bioactive materials have been developed [1,2].
Most of them are ceramics and metallic materials.
Since materials which do not break off but deform to some extent and absorb the fracture energy even under highly loaded condition are desirable for bone substitutes, this composites are useful as bone-repairing materials.
These composites are considered to be useful as bone-repairing materials.

Materials and Methods Raw materials: HDPE was obtained from ADV System Technology at 2.0 g/10 min melt flow index (2.16 Kg/190 oC) with the density of 0.9537 g/cm³.
In this situation, ASTM Designation E9-89 was applied for the slenderness ratio of polymeric materials, where the slenderness ratio, l/d (d = 12 mm) of the specimen is ~ 1.5.
HDPE/SD composites were tested under high strain rate of 650 s-1, 900 s-1, and 1100 s-1, respectively Results and Discussion: Strength and rigidity properties: Strength is commonly referred to the capability of a material to hinder the fracture under applied stress either at low or high speed [11], while rigidity of a material signifies the material’s ability to resist deformation.

The isotherms of all anionic clays showed H3 loops, characteristic of mésoporeux materials [40, 41].
In addition, we can say the same thing in the case of micropore materials.

Micro Magnetic Field Sensor Based On Terfenol-D/PZT/Terfenol-D Magnetoelectric Composites Yang Zheng1, a, Dan Xie1,b, Jing Ma2 , Tianling Ren1 , Litian Liu1 1Institute of Microelectronics, Tsinghua University, Beijing, CHINA 2Department of Materials Science and Engineering, Tsinghua University, Beijing 100084, CHINA azhen-y@mails.tsinghua.edu.cn, bxiedan@mail.tsinghua.edu.cn Key words: ME Composites, Magnetic Sensor, PZT, Tefernol-D Abstract.
Although the ME effect has drawn much attention, only small ME coefficients have been observed in single-phase materials and they are bound to low temperature.
In recent years, ME effect has been observed in composites, which is hundreds of times higher than in single-phase materials[2]-[5].
The giant ME effect comes from strong coupling between the magnetostrictive material and the piezoelectric material of the composites.

Under these circumstances, at time t1 (see Figure 1(a)) where the vibration speed (Vau(t)) exceeded the extrusion speed (Ve1), the die shoulder separated from the flow material.
The separation continued until the contact between the die shoulder and the flow material resumed again at time t2 (see Figure 1(a)).
Frictional shear stress (τ) for all of the contact surfaces were defined as: Where m was friction factor and k was shear flow of material.
