  1. Composite Stiffness Property Prediction

    07 Aug 2017

    Micromechanical models for the composite axial tensile, transverse tensile, and axial shear are combined into one tool with the objective of comparing their effectiveness as property prediction methods.  Rule of mixtures models (ROM) and the composite cylinder model (CCM) results for...

  2. 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...

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

    11 Jul 2017

    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...

  7. MUL2-UC Beam modeling of periodically heterogeneous composites

    13 Jun 2017

    The micromechanics code MUL2-UC is developed to work as an efficient and high-fidelity tool for the computation of the effective stiffness matrix and the recovering of the local fields of periodically heterogeneous composite structures. The main novelty is that higher-order beam theories are...
