Micromechanical models for the composite axial tensile, transverse tensile, and axial shear are combined into one tool with the objective of comparing their effectiveness as property prediction methods.  Rule of mixtures models (ROM) and the composite cylinder model (CCM) results for...

Woven fabrics UMAT- a coupled material model

02 Aug 2017 | Contributor(s): Ali Roumani

One of the advantages of woven fabrics over unidirectional prepregs is their superior formability thanks to the large shear deformation capability. There exists, however, a limit on the shear deformation of woven fabrics, namely the wrinkling. Applying tension to delay wrinkling during forming...
