Energy consumption in mechanical systems using a certain nonlinear degenerate model
In modern engineering materials used for creating effective ballistic shields, the issues of evaluation of their energy consumption are extremely important. The paper presents a new way of solving this problem using a certain degenerate model with dry friction. This method involves the use of specially derived identification equations which describe the decrease in potential energy of the system during its vibratory motion induced by a single pulse load. Analytical considerations have been verified using a computer simulation technique for selected examples.
