Stifness matrix of a “semi-infinite” finite element for a weakly compressible material based on the moment scheme

The stiffness matrix of infinite hexahedral finite element for fiber composite material based on the moment scheme

“…Therefore, the magnitudes of the maximum compressive stresses are significantly different from the other two cases. When using formulas (6) and 7the quality of representation is the same, formulas (7) give 6-8% higher values of stresses than formulas (6). The maximum stresses increase with increasing f because increasing the content of stiffer fibers increases the rigidity of the entire structure.…”

“…Analysis of underground excavations for unlimited areas based on infinite element method is shown in [5]. Construction of the stiffness matrix of infinite finite element for isotropic weak elastic material is developed in threedimensional case [6].…”
