Carbon nanotubes (CNTs) are the ultimate reinforcing materials for the development of an entirely new class of composites.
In this paper, nano-structure having hexagonal representative volume element (RVE), theory of elasticity of anisotropic materials and finite element method (FEM) are used to investigate the effect of helical CNT morphology on effective mechanical properties of nanocomposites.
Introduction Carbon nanotubes, discovered first by Iijima in 1991 [1], possess extremely high stiffness, strength and resilience, and may provide the ultimate reinforcing materials for the development of nanocomposites.
Investigation the effects of carbon nanotube morphology of such nanoscale materials is one of the necessary and significant tasks for the development of nanocomposites.

Introduction Ultimate axisymmetric punching capacity of concrete slabs are problems related to the three dimensional stress state analysis and the failure properties of the brittle materials.
Among them, the twin-shear failure criterion has abilities to reflect the failure properties for all kinds of materials and take the other existing criteria as its one special case [3, 4].
Hill [20] had pointed out that the Harr-Von Karman’s perfect plastic assumption is not inconsistent with the materials.

It also provides a reference value in the selection of subgrade materials in aeolian soil area.
Test material and method Test material.The cement in this test is Portland Cement 425, gravel, aeolianite, fly ash from local materials nearly.
Take the JH series produced by Jilin Tianyi Building Materials Company as fly ash activator.
In the lack of natural sand soil wind-blowned region, use cement, fly ash to stable wind-borned sand as pavement materials, can doing local materials, reduce the cost of projects

It is very important for the application of molybdenum in structural materials to research and develop new molybdenum alloys.
But ceramics exhibit poor toughness which restricts their application for structural materials.
Raw materials of experiment adopt analytically pure Al(NO3)3·9H2O (purity higher than 99.0%) and analytically pure MoO3 ( purity higher than 99.0%).
