Numerical modeling for forming of woven composites based on 3D strain gradient elasticity
Deyong Sun, Shuyuan Li, Shan Tang, Weizhao Zhang
Abstract: To accurately simulate the forming process of woven composites, various constitutive laws of woven composites based on continuum mechanics have been developed to capture the complex deformation behaviors of the materials. However, spurious wrinkles may occur in the simulation of 3D bending deformation due to the relatively low plane shear stiffness compared to the fiber compression. In this paper, the 3D constitutive law is established based on the strain gradient theory to capture bending deformation properties of woven composites. It can be generally applied to numerical analysis through different length-scales, including microscale, mesoscopic and macroscale. Meanwhile, this constitutive law is newly implemented into the commercial finite element software Abaqus/Explicit in the form of a user defined subroutine VUEL.
