Introduction The yield characteristics for materials vary significantly due to their complicated microscopic structures, even though for the isotropic homogeneous materials [1-3].
The value of and are concerned with the stress states in materials.
For materials under the stress states, the there principal stresses are (15) .
It shows that this new criterion can reflect the yield characteristics better for different materials.
When materials are in the state of yield, themay be approximately 0.5 [6, 7, 15].

The main reasons are: ● The disorder of the organization, management and use of materials lead to a large difference between the production gradation and design gradation.

The fractional dynamics equation of a viscoelastic two-member truss system, in which fractional derivative model introduced to simulate the materials’ characteristics, is proposed.
With the rapid development of materials science, a large number of new polymer material or polymer matrix composites are widely used in civil, mechanical, aerospace and other engineering fields in these years, and it is formed a special kind of intelligent viscoelastic structure.
