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...

Puck Failure Criteria

31 Jul 2017

Composite materials have been established as competitive materials during the last few decades due to their high strength to l ow weight ratio among other advantages and are widely used in many industries. A recent study has found that the industrial usage of composite failure...

Injection Overmolding Manufacturing Process Simulation

29 Jun 2017 | Online Presentations

Injection over-molding or hybrid molding is a high-rate composites manufacturing process for fabrication of structural components with complex geometries.  The structural backbone is provided by a continuous-fiber woven prepreg while the geometric complexity is realized via injection...
