Hi,
I have been trying to solve a system consisting of 3 linear spring elements using the Newmark's method to find displacement, velocity and acceleration in Matlab. I followed the instructions shown on page 5 of the paper attached and my code does not seem to be working as the displacement values keep increasing. Does anyone know whether the instructions I am using are correct...? Also does anyone know a similar system for which a code has been written already so that I can compare my results.
p.s. I've aslo attached the equation of motionfor a single element. Effectively I have similar system including 4 by 4 mass and stuffness matrices and 4 by 1 displacement and acceleration matrices.
Any hints and tips would be appreciated.
Many Thanks!
