RESEARCH OF THE IMPACT BEHAVIOR OF A PARTICLE IN INTERACTION WITH THE LINER BY THE FINITE ELEMENT METHOD
Purpose of the work: determination of the characteristics of the interaction between the particle and the lining in cold gas-dynamic spraying. Research methods: the finite element method was used in modeling the process. Results: In this work, the impact behavior of a particle upon interaction with a lining during cold gas-dynamic spraying is investigated. In the process of performing the work, the FEM ABAQUS / Explicit program was used. The study consists of the following stages: simulation of a particle and a substrate using various parameters of the Johnson-Cook steel material, particle sizes and other parameters; analysis of the effect of different particle impact velocities for different Johnson - Cook parameters (the same for a particle and a substrate), an analysis of previous results at different temperatures (for particles) is ISSN 2308-5312 Наукові праці ДонНТУ.
