Abstract: The paper considers the propagation of explosive loads in an infinite viscoelastic cylinder. The problem is posed in cylindrical coordinate systems. Using the Nave equation and the physical equation, a system of six differential equations is obtained. After a simple transformation, we obtain a spectral boundary value problem for a system of ordinary and partial differential equations with complex coefficients, which is then solved by the method of straight lines and orthogonal Godunov run with a combination of matrix differential equations solved by the new Mark method.
Key words: viscoelastic cylinder, Nave equation, stresses, deformation, ordinary differential equation, modified finite volume method, complex coefficients, S. K. Godunov method.
