Is it possible to homogenize aperiodic/partially periodic structures using 3D FEA?
Closed | Responses: 1
apart from MSG? is there any alternate way to predict effective properties using 3D FEA for aperiodic/ partially structures such as honeycomb core, circular fiber...

Composite Stiffness Property Prediction
out of 5 stars
07 Aug 2017 | Contributor(s):: Joshua Morris
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...

Computational evaluation of effective stress relaxation behavior of polymer composites
11 Jul 2017 | 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...
MUL2-UC Beam modeling of periodically heterogeneous composites
13 Jun 2017 | Contributor(s):: Alberto Garcia de Miguel
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...
