Constitutive modeling for time- and temperature-dependent behavior of composites
08 Jan 2020
Structural integrity, durability, and thermal stability represent critical areas for adequately modeling the behavior of composite materials. Polymeric matrices are prone to have time-dependent behavior very sensitive to changes in temperature that influence the effective properties of the...

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...
