  1. 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...

  2. 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...

  3. Variational asymptotic micromechanics modeling of heterogeneous piezoelectric materials

    24 Jul 2017 | Publications | Contributor(s):: Tian Tang, Wenbin Yu

    In this paper, a new micromechanics model is developed to predict the effective propertiesand local fields of heterogeneous piezoelectric materials using the variational asymptoticmethod for unit cell homogenization (VAMUCH), a recently developed micromechanicsmodeling technique. Starting from...

  4. Micromechanical investigations of polymer matrix composites with shape memory alloy reinforcement

    18 Jul 2017 | Publications | Contributor(s):: Tian Tang

  5. Numerical characterization of effective fully coupled thermo-electro-magneto-viscoelastic-plastic response of smart composites

    18 Jul 2017 | Publications | Contributor(s):: Tian Tang

  6. Computational evaluation of effective stress relaxation behavior of polymer composites

    11 Jul 2017 | Publications | Contributor(s):: Tian Tang, Sergio D. Felicelli

    This paper presents a micromechanics model to characterize the effective stress relaxationstiffness of polymer composites. The linear viscoelastic behavior of polymer material wasmodeled by hereditary integral. The proposed model was established based on thevariational asymptotic method for unit...
