This study presents a transient non‐linear finite element analysis within the realm of a multibody dynamics formalism. The governing equations are derived using the concept of virtual work. Unlike others, this analysis includes the non‐linear strain measure and rotation explicitly in order to capture the correct dynamic stiffening in anisotropic shells. The finite element analysis invokes the co‐rotational form of the updated Lagrangian formulation and utilizes a flat shell element.
