Considering the Sherwood-Frost constitutive relation and contribution of gas to the strength of the material, the macroscopic phenomenological constitutive relation of this material is developed. 1 Introduction Aerogels are nanostructured materials with attractive properties such as highly porous, low-density [1] and low thermal conductivity, and can be used as color-filter materials [2], catalysts [3, 4], adsorbents [5] and thermal insulation materials.
Due to these properties, aerogels have a widely application in optics, aeronautics and astronautics, electrochemistry, military and function materials.
The greater of the strain rate, the bigger of the collision speed of gas molecules, so the greater contribution of the gas on the strength of materials.

Since these materials serve important functions in systems, quantifying changes occurring in the material’s chemical, physical, and mechanical properties over the system lifetime is observable[3].
The result is a large scatter for the results of standard testing methods and a distinct difficulty in obtaining rational assembly stress assessments for these materials.
Followed, prediction of 10,000 sets of assembly stress is completed by Monte Carlo random sampling materials model parameters.

NbF5 and CrF3 catalysts effects on synthesis and hydrogen storage performance of Mg-Ni-NiO composites Qi Wan, Ping Li *, Teng Wang, Xuanhui Qu Institute for Advanced Materials and Technology, University of Science and Technology, Beijing 100083, China Corresponding author: bj60106531@sina.com Keywords: Hydrogen storage; Mg-based materials; cryomilling; hydrogen storage performance; kinetics; NbF5 Abstract: Two kinds of novel materials, Mg-1.6mol%Ni-0.4mol%NiO-2mol%MF (MF=NbF5, CrF3), along with Mg-1.6mol%Ni-0.4mol%NiO for comparison, were examined for their potential use in hydrogen storage applications, having been fabricated via cryomilling.
Carbon nanotubes seem to be convenient adsorbent materials, but hydrogen storage capacity limits their potential for hydrogen storage.
It has been shown that Mg-based hydrogen storage materials, prepared with cryomilling, have excellent properties [18].
Firstly, Mg-based hydrogen storage materials fabricated by cryomilling have outstanding activation performance.
