Introduction Fiber composites are an emerging class of structural materials widely used in many critical applications such as national defense and space technology.
Because low-density, high specific strength, high specific stiffness and the characteristics of to design properties by controlling bonding and materials processing technology of the fiber and matrix, the composite materials in engineering is very promising.
Actually, the distribution of material within the micro-structure is variety, and the periodic micro-structure is the extreme of the material from completely disordered to a strict ordered of the internal structure, also the natural composite material contains many period or similar period of the micro-structure, as the development of material manufacturing technology, a number of reinforcement periodic-accurate distribution of new materials will emerge.

With the cylindrical magnetic abrasive apparatus designed and made by the author, a series of experiments on finishing the cylindrical surfaces of nonferromagnetic materials and ferromagnetic materials are carried out.
Choosing the optimized technical parameters, , the surface roughness of ferromagnetic materials changes from Ra 0.825µm to Ra 0.045µm after the 12-minute finishing experiment; the surface roughness of nonferromagnetic materials changes from Ra 0.434µm to Ra 0.096µm after the 20-minute finishing experiment.
In this paper, we study the mechanism of MAF, put forward four self-sharpening modes of abrasive particles, make experimental investigations in finishing the cylindrical surfaces of nonferromagnetic materials and ferromagnetic materials, and discuss the influence of MAF technical parameters on finishing performance.
Experimental Results and Discussion In the experiment, the self-made cylindrical magnetic abrasive apparatus and MAC-series abrasives are adopted. 45-steel (ferromagnetic materials) and 1Cr18Ni9Ti stainless steel (nonferromagnetic materials) are chosen as experimental materials.

Introduction In recent years multifield materials for the development of smart structures applications are receiving increasing attention.
This is the case of piezoelectric materials, widely applied in smart devices and structures due to the coupling effects between mechanical and electrical fields.
Composite materials and structures are often applied in different loading conditions like static, timeharmonic and impact or time-dependent loading.
The dynamic crack analysis is an important issue in material sciences and engineering applications of composite materials.
The corresponding results have a direct relevance to the design, optimization and dynamic fracture mechanics of composite materials.

The properties of these materials can be significantly different from the behavior of their parent materials [9].
Nano-copper oxide is a widely used material and is applied as catalyst for superconducting materials, sensing materials, thermoelectric materials, ceramics, glass and others.
