In a simple form, i am integrating some differential equations in matlab.
One of this equations need the strain of the beam (in this case). As the beam is vibrating i have the information of the displacement, who varies in time (vibration).
In this question i want a function who gives the...
No, is a project of mine.
I am using a specific material to control the vibration of the beam, this material is a wire. I have tried without the angle (paralel to the beam) but in this mode the force that i need is much high.
As my material varies is force based on his strain i need this...
Well, i have a cantilever beam where i have the displacement of the tip of the beam (y axis) data from a vibration of this beam. In the tip of the beam is a steel wire attached, pulling up the beam with an angle (30º for example).
I want to know if exists a form to obtain the strain of the wire...
Sorry for the incorrect use of some constants,
the deflection is Ya=X(1) and do not have relationship with the x who is based in the lenght of the beam.
Thanks for all the answers
PhantomJay, i have tried here:
X(1)=(P*(L^3))/(3*E*I) %%%Equation of the deflection, where x(1) is the variation of the deflection in time
P=(X(1)*3*E*I)/(L^3)
Substituing in the equation
Stress=Mc/I
Strain=Stress/E
Strain=(X(1)*3*I*c*x)/(I*L^3)
Is that correct?
Well, i have made:
Stress=(ya*3E*I)/(A*L^3)
Strain=Stress/E
Strain=(ya*3*I)/(L^3*A)
Where:
A= Area
I=Inertia
E=young modulus
My question now is, as i am integrating this system (Matlab, ode45) i need to derive this equation, no?
Hi,
Well i have a system with a excited (in y axis) cantilever beam. I struggling to obtain a expression that gives the strain based on the dislocation y.
I know that the displacement of the beam is given by:
Ya=PL^3/(3EI)
but how i make a correlation between this and the strain of the...
