In the pursuit of producing high quality, low-cost composite aircraft structures, out-of-
autoclave manufacturing processes for textile reinforcements are being simulated with
increasing accuracy. This paper focuses on the continuum-based, finite element modelling
of textile composites as they deform during the draping process. A non-orthogonal
constitutive model tracks yarn orientations within a material subroutine developed for
Abaqus/Explicit, resulting in the realistic determination of fabric shearing and material draw …
