Hi every one !
I am a final year Engineering student of IIT Madras, India. I am doing a project(finite element analysis of a structure) which requires the solution of a system of second order differential equations. equation looks like below:
[M][U"]+K=[F(t)]
M : Mass Matrix of size 202x202
K: Stiffness matrix of size 202x202
F(t): time dependent force matrix of size 202x1
M , K and F(t) matrices are known
U: displacement matrix for nodes , size 202x1
U'': double derivative of displacement matrix, size 202x1
Initial conditions :
=0 at t=0
[U'']=0 at t=0
to find :
at t
this is the displacement matrix for the nodes of the system of elements
I will be extremely happy if someone could come out with a MATLAB code to solve this problem, this will be a great help for me as I am struggling with this from past few days and not able to make any progress in the project. Thanks a lot.. eagerly waiting for reply..
