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.

Generally, welding database research focused on materials management, welding procedure qualification and welder qualification exam and so on.
Tsinghua University developed a steel pressure vessel welding and management system for Beijing Yanshan Petrochemical construction and installation company, which can calculate and aggregate consumption of welding materials, and generate process planning.
In 2001, China began to start National Science and Technology Data Sharing Project.

The need for light weight and durable materials are fulfilled by various metals and its alloys.
One of the important materials that are widely used in this category is aluminium and its alloys.
In some materials the property changes because of the heat input generated during welding.
Also it has comparatively higher mechanical property values than the materials welded without SiC particles addition were discussed elsewhere [21].
