TO ASSESS THE RELIABILITY OF THE NUMERICAL METHOD WHEN THE INTERFERENCE OF THE ELASTIC WAVES OF STRESSES IN AN INFINITE PLATE (THE IMPACT IN THE FORM OF A STEP FUNCTION)
The information about modeling of physical reliability and mathematical accuracy of the numerical method is given. The problem of interference of elastic stress waves is solved. The function of Heaviside is taken as an influence. To solve this problem, the equations of wave computational mechanics are used. The technique, algorithm and complex of programs for solving linear non-stationary dynamic problems are developed. The basic relations of the finite element method are obtained by dynamic equilibrium. In solving complex problems there are problems of assessing the reliability of the results.
