Design algorithm of rational fiber trajectories in arbitrarily loaded composite plate

Autor: Andrei Malakhov, Alexander Polilov, Alexey Polilov

Publikováno v: Journal of Machinery Manufacture and Reliability. 46:479-487

The correctness of the algorithm for the plot of rational fiber placement trajectories, assuming their equally stressed state, which is equivalent to the exclusion of shear stresses at the fiber–matrix interface, has been rationalized. An iteration

Designing branching or shaped composite elements by analogy with the structure of treetops

Autor: Alexander Polilov, Nikolay Tatus

Publikováno v: Journal of Machinery Manufacture and Reliability. 46:385-393

The analogy of the bending flexibility of shaped beams of the constarea class (with a constant area of the cross section) and branching composite structures that resemble a treetop with a constant sum of the areas of sections of the branches (Leonard

Design of composite structures reinforced curvilinear fibres using FEM

Autor: Andrei Malakhov, Alexander Polilov

Publikováno v: Composites Part A: Applied Science and Manufacturing. 87:23-28

This paper describes a method of modelling a curvilinear reinforcement structure, for a composite plate with a hole that allows trajectories of fibres to be adapted to geometric discontinuities (holes, notches, bolts, etc.). For this method, it is as

Mechanisms of stress concentration reduction in fiber composites

Autor: Alexander Polilov

Publikováno v: Journal of Applied Mechanics and Technical Physics. 55:154-163

Various models of subcritical fracture that make it possible to explain the significant decrease in the effective stress concentration factor compared with the theoretical value are described for fiber composites with a polymer matrix. The necessity

Construction of trajectories of the fibers which bypass a hole and their comparison with the structure of wood in the vicinity of a knot

Autor: Andrei Malakhov, Alexander Polilov

Publikováno v: Journal of Machinery Manufacture and Reliability. 42:306-311

Attachment fittings remain a weak point of composite structures owing to traditional techniques of drilling holes for rivets or bolts. An alternative version is suggested by Nature by creating a “branch-trunk” connection without fiber cutting. Tw
