@Greg Locock
Honestly I did not get what you said
could you please give me the Matlab code you used to get your answer?
My problem here is not the answer but how to get k for each value of Z without the loop.
Kindly send me the code
Thanks

Hi
I have this symbolic 2x2 matrix in Matlab. z is A Symbolic variable
k(z)= [ z+1, z^2; exp(z), z^3].
I need a value of k(z) for z=1:N
How to do this without a loop '' FOR''
Thanks
Hi EVERYONE
Attached is the SIGNAL in FIGURE 1 its Power Spectral Density( PSD ) in FIGURE 2 as well as the matlab code to get FIGURE2.
How will I get the Normalised Power Spectral Density of FIGURE 3?
what to add in the matlab code?
its a dynamic response of a wind turbine
Thanks...
Thanks once more for your reply!!!
I used RPs for flanges and it kept showing me this message:
''2 nodes are missing degree of freedoms. The MPC/Equation/kinematic coupling constraints can not be formed. The nodes have been identified in node set ErrNodeMissingDofConstrDef''
Till I have decided...
@ FEA way Thanks for your reply.
I tried to do exactly what you explained but THE problem is, The point belonging to a connector must be tied to a connector(as we did with flange).
Now I DON'T REAALY now how to tied a point to a connector!!
Any suggestion should be welcomed!!!
Hi Everyone
I want to connect a visco damper(VD) on the steel-made flange of a tower in ABAQUS. The VD is modelled USING CONNECTORS. The connectors was linked to a flange using the RP (which are tied to a flange) as per the pictur attached.
Im not getting the expected results. Now from a...
@Erik Panos Kostson (Structural)
Just to have the full understanding of the following lines concerning nonlinear damper
*Dashpot, elset=Springs/Dashpots-1-dashpot, nonlinear
-0.001,-10
0.001,10
0.002,20
0.003,30
0.004,40
0.004,1000
Is the first COLUMN force? if yes whats the unit(F)?
Is the...
I want to use the viscous damper in abaqus. I firstly used spring/dashpot but it didn't work. Now I realized the best way is to uses the nonlinear dashpot element.
Can someone explain me how to do it?
Thanks
Hi
I want to mount a TMD (m,k,c) on my beam-like structure in Abaqus. The beam has a mass at its top(point mass in abaqus). Practically, a tmd should be placed inside the top mass. Its seems impossible to do this as the top mass here is a point!!!
Should a TMD mass be also a point mass?
if yes...

KLR is cross coupling (lateral-rotational) stiffness of slender pile for homogeneous soil.
For example the DOF of KL and KR here are 1 and 6 respectively.
Whats KLR DOF?
