“…Regarding the material modeling, there are different micromechanical homogenization methods for composite materials (Li and Wang, 2008). For instance, Lin et al (2016) examine different micromechanics methods, most of which are based on the Eshelby inclusion theory (Eshelby, 1957), to evaluate the effective moduli of soft Neo-Hookean composites. The Eshelby theory is later extended for the analysis of plates and shells.…”

This paper presents two different formulations for the modeling of thin laminated composite shells, which do not need any numerical integration through the shell thickness. The two proposed formulations are suitable for thin rotation-free shells based on Kirchhoff–Love kinematics. The composite shell is modeled in the framework of equivalent single layer (ESL) theory and the kinematics are adopted from classical laminated plate theory. The two formulations allow for any desired nonlinear isotropic or anisotropic material model as well as arbitrary large strains and deformations. The presented shell models can be used to analyze any arrangement and material behavior of the laminate layers. The FE solution is based on isogeometric analysis (IGA). Quadratic NURBS-based elements are used to ensure the smoothness required for the analysis of thin shells. The robustness and accuracy of the formulation is demonstrated by various numerical examples.
