Challenges of the creation of a mechanical stiffness matrix for such a complex material are described in this paper along with simplification ideas and solutions.application/pdffolyóiratcikkOpen Accessby the authorshttps://doi.org/10.21791/IJEMS.2019.1.41.International Journal of Engineering and Management Sciences142498-700X
