“…Hence, to describe the continuum properties in modeling the compaction process using methods of continuum mechanics, the sintering theory for porous bodies [3,4], creep theory [5,6], and ideal elastoplastic model [7][8][9][10][11][12][13] are employed. These papers mainly consider the compaction of a strand of unidirectional composite fibers under isostatic or uniaxial pressing.…”

The formation of internal boundaries in a unidirectional fiber strand during isostatic and uniaxial pressing in plastic state is studied. The process is modeled using the finite-element method (FEM). An ideal contact elastoplastic problem for a hexagonal fiber strand undergoing plane deformation is solved taking into account friction at the boundaries. For angles of 0°, 30°, 60°, and 90° between the normal to the contact area and the pressing direction, the contact area width, change in the contact area slope, and the radius vector of the cross-sectional boundary of the fiber inside the pore channel as functions of density are determined for the friction coefficient at the boundaries of fibers equal to 0 and 0.5.
