MATLAB: Contour plot for nodal displacement

contournodal displacement

Hi,

I am using image processing and have x and y location of each node (as two vectors) and also y displacement for each node.I am just wondering how I can show the y displacement contour for nodes (nodal displacement)?

here is the x, y and u data attached file.

MATLAB: How to plot time vs displacement

Demo EXample:

t0 = 1 ; t1 - 10; dt = 0.01 ;
u = @(w,t) = cos(w*t) ; 
t = t0:dt:t1 ; 
w = 2*pi ;
s = u(w,t) ;
plot(t,s)

Are you sure that the equations are correct? The solution you posted does not satisfy the initial conditions.

Generally, such a problem can be solved using the Symbolic toolbox

syms x(t) w A
dxdt = diff(x);
dx2dt2 = diff(x,2);
ode = dx2dt2 == -A*w*sin(dxdt);
cond = [x(0)==pi/4 dxdt(0)==0];
sol = dsolve(ode, cond)

or ode45() can be used for a numerical solution.
