Introduction Recently, Ca3(VO4)2 artificial crystal materials have attracted increasing interests due to their potential application in solid state lasers, luminescent, and ferroelectric materials, etc.
Experimental Analytical reagent grade of NH4VO3, Ca(NO3)2·4H2O, (NH4)2HPO4 and Bi(NO3)3·5H2O were used as starting materials.
Eu2O3(99.99 %) was purchased from Shanghai Yuelong New Materials Corporation.

Distortion Simulation of Unsymmetrical Composite Laminates Using the Finite Element Analysis Method Min LIa, Bao-yan ZHANGb and Xiang-bao CHEN Beijing Institute of Aeronautical Materials, Beijing 100095, China a lm0708@yahoo.com.cn, bzhangbaoyan0916@yahoo.com Keywords: unsymmetric laminate; composite; FEA; distortion; simulation Abstract: Unsymmetric composite laminates were benefit to reducing the structure weight of some aircrafts.
Introduction Composite materials are very important for aerospace industry due to their light weight and high stiffness/weight ratio.
And further more composites have superior performance over traditional materials, including the fact that composite materials could be tailored to meet specific design and loading requirements.
Material properties The unsymmetrical composite laminates were manufactured by typical fabrication process of 3234/T300 epoxy/carbon fiber composite, which was produced in authors' institute.

Shape memory polymers are stimuli-responsive materials able to adaptively store a temporary (deformed) shape and recover a 'memorized' permanent shape under an external stimulus.
Introduction Shape memory polymers (SMPs) are a class of polymeric materials that can be formed into a specific primary shape, reformed into a stable secondary shape, and then controllably actuated to recover the primary shape.

The basic idea was to establish a periodical international forum presenting multiscale approaches in fatigue and fracture of materials.
Nearly 180 scientists from 27 countries all over the world presented a variety of fundamental relations between structural and mechanical characteristics of materials.
