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...
