Abstract
Background
One of the basic motives for carrying-out the analytical study of delamination reported in this paper is the fact that there are many situations in which multilayered beams are used as moving components in various engineering applications. Very often these components move with acceleration. Therefore, forces of inertia have to be considered when analyzing delamination fracture.
Objective
This paper is focussed on delamination analysis of a multilayered non-linear viscoelastic inhomogeneous beam structure which rotates around a motionless axis. At the same time, a particle is moving non-uniformly along the upper surface of the beam.
Methods
The forces of inertia in the system “multilayered beam – particle” are considered and used when analyzing the delamination fracture in terms of the strain energy release rate.
Results
The strain energy release rate is derived. The integral
Conclusions
Practical applications of the analysis are presented. The beam thickness is determined by applying the analysis developed. Some important parameters related to the safety functioning of the system “multilayered beam – particle” like critical lengths of the beam and the delamantion crack are also obtained.
