Basing on isotropic material and taking the relative density of materials as design variable, SIMP approach with high efficiency is easy to be realized by program.
In other words, the iterating results under the control of local rule will ultimately determine the distribution of materials in the design domain.
(2) The distribution of solid materials in design domain through iterative process is controlled by the local rule.

While the second type suggests that making arranged layers in each part already separated according to the materials.
From the point of composite materials, this article intends to use the layered-shell element method to simulate the multi-ribbed composite panel.
All of the materials are supposed to be isotropic.
Due to the isotropic property of the materials, the concrete and the blocks can be regarded as one layer respectively.

For this reason, materials need to be developed that can adequately replace bone tissue, especially mineralized tissue such as bone and teeth.
Hydroxyapatite Ca10(PO4)6(OH)2 is particularly attractive for use for human tissue implantation due to its compositional and biological similarity to host materials [1].
The structure and physical characteristics of the materials were evaluated.

Introduction Development of technologies and materials which improve and open news possibilities in air transport has been a recurrent concern in aerospace industry.
One of the main conditionings in the selection of materials to use in structural elements is safety.
In this sense, one of the principal ways of investigation in this field is the development and control in work of materials more resistant to the different aggressive actions which can be subjected.

However, titanium and its alloys are usually considered as extremely difficult to cut materials because of their low modulus of elasticity, high chemical reactivity with cutting tool material and its high stress and strength ratio at elevated temperature makes the machining further difficult [3, 4].
