A triangular shell finite element formulation is implemented in for use with the popular open-source finite element software package Ferrite.jl. Both elastic and geometric stiffness matrices are available, allowing for the calculation of elastic deformations, stresses, and buckling in thin-walled structures. The shell element formulation utilizes linear shape functions to interpolate for membrane deformations, and considers additional quadratic shape functions to predict bending deformation while avoiding shear locking. The triangular shell element is shown to perform accurately when compared to Abaqus shell element and analytical solutions in a series of thin and thick plate examples which consider elastic deformation and elastic buckling.
