Harmonic excitation of a SDOF
Updated Thu, 07 Apr 2022 13:55:34 +0000
The exact solution of a damped Single Degree Of Freedom (SDOF) system is excited by a harmonic force is calculated . It is compared to the numerical solution provided by the Matlab built-in function ode 45, the central difference method, Newmark method and the 4th order Runge-Kutta method, the implementation of which is based on the book from S. Rao .
The repositroy contains:
- The function RK4.m, which solves numerically the equations of motion of a damped system with the 4th order Runge-Kutta method
- The function Newmark.m, which solves numerically the equations of motion of a damped system with Newmark's method
- The function CentDiff.m, which solves numerically the equations of motion of a damped system with the central difference method
- A Matlab livescript Documentation.mlx for the documentation
