LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a kind of icon instead of lines of text to create applications by using the graphical programming language.
Therefore, the Virtual Instrument Technology for inclination measurement scheme is feasible, and the methods greatly strengthen the integration of the system and portable, which is good for the future realization of engineering application foundation.

Introduction Elastic-plastic deformation of solid materials is common in engineering, but it’s very difficult to accurately describe large deformation process.

Introduction Three-dimensional (3D) braided composites are widely used in various industrial sectors, such as civil and defense, as they possess some improved mechanical properties compared to laminate composites [1].
As FEM models are always complex and the computational process cost greatly, a hybrid model to predict the mechanical properties of 3D4d braided composites is introduced in the current research, which will be convenient in current and future engineering application. 1 Geometry of 3D Braided Composite In the previous research work [3] of the author, the 3D4d braided composite material which is manufactured by four step braiding process has been divided into three parts: the inner unit cell, surface unit cell and corner unit cell, Figure 1 illustrates the three kinds of unit cells respectively.
(8) The effective engineering constants of the unit cell can then be determined in terms of Ciso-strain. 2.3 Iso-stress model If the stiffness matrices in section 2.2 are replaced by their corresponding compliance matrices, then, the global compliance matrix of the whole composite can be obtained, by Eq. 9
(9) Similarly, the effective engineering constants of the unit cell can then be determined in terms of Ciso-stress. 2.4 Hybrid model Researchers have shown that the mechanical properties predicted based on iso-strain assumption tend to be higher than experimental results, while mechanical properties predicted based on iso-strain assumption tend to be lower.
