Abstract : In this investigation, a continuum mechanics based shear deformable shell element of the absolute nodal coordinate formulation (ANCF) is generalized to a laminated shell element for application to the modeling of fiber-reinforced rubber (FRR) structure of the physics-based ANCF tire model. The complex deformation coupling exhibited in fiber-reinforced composite materials can be automatically considered in the shear deformable laminated shell element using the continuum mechanics approach, and the element lockings are systematically eliminated by the assumed natural strain and enhanced strain approaches, thereby leading to a locking-free shear deformation ANCF laminated shell element. Furthermore, various nonlinear material models can be considered for each layer in a way same as solid elements. Using the ANCF laminated shell element developed, a physics-based ANCF tire model is developed by considering the detailed tire geometry and material properties. The experimental validation of the tire model is conducted for the load-deflection curve to ensure that the fundamental structural tire properties can be correctly captured in the ANCF tire model.
