Modeling of the Interaction of a Composite Orthotropic Plate with Ice Particles

The normal interaction of ice particles with a composite orthotropic organoplastic plate is modeled scientifically. The range of interaction velocities from 80 to 500 m/s is considered. To develop a mathematical model and numerical algorithm, a coordinated series of physical and numerical experiments have been conducted on impact loading of the composite plate with steel spheres. The behavior and fracture of the composite and ice are described by the elastic-brittle model taking into account their different strengths in compression and tension. Numerical simulation is carried out by the finite element method using the software complex EFES developed by the authors. The composite plate fracture under simultaneous impact by a group of particles and sequential impact by a particle stream is investigated.
