In this work are considered new magneto-controlled materials - magnetoelastics, their elastic and magnetic properties.
It was found out that hysteresis loops for considered polymer materials have unusual character.
It is defined both by scientific interest in this "smart materials" and by perspective of their technical application.
It let us create new magneto-controlled high-elastic materials with giant value of magneto-deformation effect (up to 400%), which is shown in extension, compression and twisting of specimens in external magnetic field.

Sulfate attack of cementitious materials is closely related to the essential properties of cementitious materials and erosive environments.
Sulfate attack of cementitious materials is a complicated physical and chemical process, and it’s closed related to the essential properties of cementitious materials and erosive environments.
With the cracks expanded by sulfate attack, the performances of materials become worse in concrete.
Damaged materials are considered as the composite materials that the second phase consists of poles or cracks.
Microstructural Development and sulfate attack modeling in blended cementitious materials.

Research on Information Dissemination Channelsand Monitoring of Sports Events Jun-wa YANG Zhengde Polytechnic College, Nanjing 211106, China; 1209010138@qq.com Keywords: Sports Events, Information Dissemination Channels, Monitoring System Abstract: With the constant development of the social modernization the communications between people and people are more and more frequent; the progress of science and technology, an increase in number of communication mediums consumedly widen the information channels.
Introduction of Sports Events Information Sports events information is an important part of the information society, with the improvement of living standards, the public material culture gradually been met, the lack of spiritual and cultural health has been a new social problem at the same time.

The main direction of their development is reducing the cost of steel (14-16%), saving cement (10-12%) and saving forest materials (12-14%).
These tasks can be solved, including at the expense of reduction of material content and reduction of the cross-section of structures, due to the rational combination of concrete and steel in their joint work and through the use of high-strength materials.

Considering transverse shear deformation, Yang and Shen[3] investigated the dynamic instability of a simple supported, finite-length, laminated circular cylindrical shells subjected to parametric excitation by axial loading and covered by piezoelectric materials.
The used material constants are listed in Table1.
The material of piezoelectric layer is PZT5 or PVDF.
The material of piezoelectric layer is PZT5.

Desai developed a new device(CYMDOF) for cyclic testing of large size interfaces between structural and geologic materials and rock joints, and by using a modified Ramberg-Osgood model, he simulated loading-unloading-reloading response, lastly predictions of the constitutive model and a finite element analysis are compared with observed test behavior [3].

In conditions of not changing the chair's surface elasticity, materials as well as surface shape, body pressure distribution can be changed by adjusting the height, the surface and backrest inclination to make a more comfortable chair.
The elastic supporting structure used in the chair designed by Shi, Zhenyu is a new type of glass fiber materials, being inconspicuous in memory than steel materials, so there is no fatigue basically.
Similarly, the cushion materials need to meet the ventilation and cooling performance, so it is commonly used polyurethane foam which easily emits water vapor from the surface quickly and has good ventilation property.
