The Boundary Element Method (BEM) is one among the most popular simulation techniques employed to simulate mechanical behaviour of materials, including smart engineering materials.
Introduction The Boundary Element Method (BEM) [3-7] is a numerical technique that is quite popular when it comes to simulating the mechanical behaviour of materials, including smart materials.
The analytical formulae used here are the same as the ones that can be found in any book on the ‘mechanics of materials’ (also known as ‘strength of materials’ or ‘engineering mechanics’) or any design data handbook.

Introduction Cement concrete is one of the most common building materials, with many advantages that other building materials cannot compare with.
In recent years, people use many means to improve the concrete cracking resistance, such as optimizing the concrete mix proportion, using polymeric materials and adding fibrous materials.

To prepare materials for sheetmetal unfolded based on CATIA software became an important link in processing and forming of sheetmetal parts.
Similarly if it is 0.8, it means that the position of neutral layer lies in the place of 80 percent of thickness of sheetmetal materials.
With the development and popularization of digital technology in aircraft manufacturing enterprises, in terms of prepare for raw materials in the process of aerospace sheetmetal forming, factor K can make changes according to the actual materials, extensibility based on CATIA software.
