The resulting composites, which are a combination of fibres with plastic matrices, have excellent mechanical properties and they are used in the aerospace, energetic, automotive, engineering industry and many others, not only in technically oriented industries [1].
Linear elasticity in an orthotropic material is most easily defined by giving the engineering constants (three elastic moduli, Poisson’s ratios and shear moduli) associated with the material’s principal directions.
Engineering constants using in numerical model are given by Table 4.

Introduction Ultra-high strength steels (UHS) and high strength steels (HS) are advanced materials providing a combination of strength, ductility, toughness, high strength to weight ratio, ease of manufacturability and cost effective manufacturing.
High strength steels with fine grains possess good weldability and plastic deformability, and thus they are promising engineering materials for the future.

On Apr. 18, 2008, in the Forum on the Protection for Industrial Heritage in China held in Wuxi city, Jiangsu province, representatives, experts and scholars from many cities and departments of cultural relics unanimously agreed and suggested that we should strengthen the protection for industrial heritage amid the rapid development of economy and achieve a harmonious and sustainable development between economic growth and cultural heritage protection.
Established in 1896, Fengtian Machine Bureau (See Fig. 1) was regarded as the forerunner of the modern national industry in Shenyang; set up in 1908, the first electric light factory in Shenyang advanced the industrial civilization to a new level; founded in 1921, Fengtian Mega-iron Works was the largest national industry in Shenyang; Founded in 1923, and Zhaoxin Ceramics Company was the first company in China to make ceramics by using machines in northeast China
In sense of social significance, industrial buildings heritage served as a record of the life of common people; from the perspective of technique and science, it is of great significance to the research on the history of manufacturing, engineering and architecture; and in terms of esthetics, those remarkable buildings possess great esthetic value for their marvelous design and layout.

Introduction The thermal management of the miniaturized electronic devices has become a challenging issue in electronic industry, micro-fabrication technologies, biomedical engineering, etc.
In addition, ethylene glycol water mixture is utilised in many engineering and industrial applications such as antifreeze in car engines or transfer medium in solar heating installations [15, 16].
