Introduction In the past few decades, carbon nanotubes (CNTs) have attracted a large interest in material science and engineering because of their outstanding mechanical, thermal and electrical properties [1,2,3].
Afterwards, Ghavamian and Öchsner [10] analyzed the effect of defects on the buckling properties of nanotubes.
Geometry, mass, and applied boundary conditions are the factors which influence this quantity.

The main difficulties are therefore related to precisely model the bone's geometry and simulate its mechanical properties.
Bone's mechanical properties are dictated to a large extent by its mineral volume fraction, which lies in the range 25-45%, with a typical value of 38% for human bone.
Additional difficulty arises from variations in properties resulting from physical activity, particularly weight-bearing exercise [8], ageing (resulting from porosity variations, etc.), and other factors.
In parallelepiped specimens some properties do not affect resonant frequencies, and so they cannot be determined by a resonant technique.
The use of a non-conventional geometry is interesting, since more properties are involved in the definition of resonant properties.

By the method of numerical simulation the variation law of stress-strain with time and space around borehole of impermeable rock medium, variety law of rock physical properties parameters is studied.
It can be seen from result that development and deformation of borehole elastic area mainly affected by ambiequal ground stress value, difference of ambiequal ground stress and rock material properties so on.
Zhao Yizhong (2009)[4] comprehensive considered the role of fluid-solid coupling, the effect of dynamic-made sewing, variable fracture conductivity and other factors, established a new model of de-sand fracturing unconsolidated sandstone reservoir productivity and carried out the optimization of de-sand fracturing capacity under the influence of the factors.

Introduction In the ice engineering and Geo-science, the mechanical properties of ice are an important scientific subject, especially strength and deformation.
For large ice sheets and thick ice or snow layer, the confining pressure has significant influence on the mechanical properties of ice.
The influences of other factors such as specimen homogeneity, grain-size, density, temperature and the state of stress on mechanical properties of ice are also observed under this test (Assur, 1980).
These data should assist in the standardization of laboratory testing procedures for the determination of the mechanical properties of artificial ice.
As is evident from the figure, the stress-strain curves of artificial ice are significantly affected by confining pressures.

Over last decade, intensive studies to the improvement in sintering property of β-TCP have been conducted over the world.
In addition, Ca/P ratio affected the transition temperature.
Hysun-Seung Ryu [5] also confirmed the Ca2P2O2 affected the sintering property of β-TCP, but much Ca2P2O2 have been observed in the final products.
Based on these factors, our work is to investigate the effect of Ca2P2O2 and CaCO3 addition on the phase transition and sintering behavior of β-TCP in order to improve the compressive strength and reduce impurity of porous TCP ceramics. 2.
