Lvov // Tomsk State University. Journal of Mathematics and Mechanics = Вестник Томского государственного университета. Математика и механика. – 2015. – Vol. 35, № 3. – P. 60-68.https://repository.kpi.kharkov.ua/handle/KhPI-Press/25081The paper is devoted to the research of the effective characteristics of 3D orthogonal nonwoven fibers composites. The results were received via ANSYS software package. In this research a volume element of fibers in cubic unit cell is considered. The effective elastic properties of fiber reinforced composite have been defined by the numerical stress analysis of the unit cell.encompositefibereffective elastic constantsnumerical methodArticle10.17223/19988621/35/8
