Short notes
A comparative analysis of methods for solving equations in the nonlinear elasticity theory
M. V. Kozlov, S. V. Sheshenin Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
In this paper we describe the way of practical solution of the variational equation in geometrically and physically nonlinear problems of deformable body mechanics. A system of a large number of nonlinear ordinary differential equations usually appears in such problems. The Euler method is typically used in this approach. We propose to use a Runge–Kutta method and multistep methods and consider the solution complexity in terms of computing cost to find a method that provides a more efficient solving procedure of nonlinear problems.
Key words:
rubber-cord, composite, nonlinearity, variational equation, linearization, finite element method, Euler method, Newton method, Runge–Kutta method, multistep method.
