No.37 material models are selected, which is a thick anisotropic material mode.
Blank material uses B501C, with a thickness at 2mm, and its Poisson's ratio is, Young'sllet mate modulus is,Yield strength is, Hardening coefficient is 0.24, the anisotropy parameters is 1.77.
Although it can shape, the materials’ biggest thinning rate was 3.45%, which cannot achieve the required strength.

Therefore, this research aims to determine the influence of adhesive bonds on the air permeability and hand of knitted materials.
Materials and Methods Eight commercially available polyester knitted fabrics containing from 4 % to 20 % elastane were investigated in this research.
The surface density of knitted materials was determined according to LST EN 12127 standard [11] using the precise electronic balance "Kern&Sohn" EG420–3NM with 0.01 g accuracy of sample mass determination.
Typical pulling curves of both control (a) and bonded (b) specimens of the investigated knitted materials.

For example, in the bending of sheet metal, some materials’ bending compensation values are unknown, the bending coefficients have to be obtained by experiments.
Then technologists can choose materials for different parts by using the unfold drawings.

The Uniform Strength Variable Cross-section Component can save materials in the project.
It has a good damping property, saving materials, reducing weight and so on.
Example In general, if the geometric dimensions and material properties are normal distribution random variable, deflection and material properties are mutually independent random variables.
The cross-section is not plane after deformation by shear stress, and beam span and height of cross section ratio is greater than or equal to 5 in Mechanics of materials.
