A viscoelastic approach for modeling bending behavior in finite element forming simulation of continuously fiber reinforced composites
07 Aug 2017 | Publications | Contributor(s):: Dominik Dörr, Fabian J. Schirmaier, Frank Henning, Luise Kärger
An approach for modeling rate-dependent bending behavior in FE forming simulation for either a unidirectional or a woven/bidirectional reinforcement is presented. The applicability of the bending model to both fiber architectures is guaranteed by introducing either an orthogonal or a...
A Benchmark Study of Finite Element Codes for Forming Simulation of Thermoplastic UD-Tapes
07 Aug 2017 | Publications | Contributor(s):: Dominik Dörr, W. Brymerski, S. Ropers, D. Leutz, T. Joppich, L. Kärger, F. Henning
For Finite Element (FE) simulation of composite thermoforming processes, either commercially available codes or multi-purpose FE solvers can be applied. In this work, the commercially available codes AniForm and PAM-FORM, as well as two approaches implemented in the multipurpose FE solvers...
A Code for Flexural Analysis of Thin-Walled Composite I-Beams with Sandwich Web and Bond-lines
02 Aug 2017 | Downloads | Contributor(s):: Mo E. Asl
Composite I-beams have extensive applications in the aerospace industry, construction and light-weight engineering structures. In the utility-scale wind turbine blades, the spar-caps and the shear web compose an I-beam structure which is referred to as the backbone of the blade carrying the...
Woven fabrics UMAT- a coupled material model
