I do not remember axactly, as this is quite an old post, but I think the problem had something to do with angle conversion from degree to radian or vice versa...that is why the amplitude was not coming out correct...but once correct, the results were beautiful :D
Try playing around with...
Reference is to the formula for stress intensity factor :
K_I(mode I) = beta*nominal stress*(pi*crack dimension)^1/2
now the question is that
1.ductile:
if I use the value of fracture toughness K_c in place of K_I and yield strength in place of nominal stress what will the value of...
Any specific reasons for this ? there is a reason MATLAB asks for separate file for better integration techniques and besides it makes job easier and cleaner.

When the term uniaxial comes I imagine something being pulled or pushed in one direction only. Confusion is that I read online http://enpub.fulton.asu.edu/imtl/HTML/Manuals/MC105_Cantilever_Flexure.htm" that a cantilever beam loaded at the end is also in uniaxial stress. This is what I can not...
I am trying to replicate a JAVA based applet on MATLAB. Applet can be seen http://www.engr.colostate.edu/~allan/thermo/page6/EngineParm1/engine.html" .
The theory behind the functions of the applet is http://www.engr.colostate.edu/~allan/thermo/page6/page6.html" .
It is actually a finite...
Can someone please explain the picture attached below ? It has been taken from a lab where the supervisor actually failed to tell what is the remote sensing bulb doing attached to a condenser. I would like to know that why is it there and is the wire that is sticking out a capillary tube? If not...
Homework Statement
A railway bridge of 80ft span with two tracks is supported by two main steel girders of I-section. The girders are 7ft deep between the centers of the flanges. If the dead weight of the structure between the abutments is 200 tons and the weight of each train of carriages is...
I have got the steady state value but how do I get the time response ? Laplace Transform ? Isn't there some shorter method ? This is because I have got a zero as well in the PI controller so the general formulae doesn't work..Any approximation ? I don't want to go for any tedious method...
Does that mean that the terms risetime, settling time and overshoot etc have no meaning at all for a pure derivative controller ? But when I think again I get confused that there should be some settling time formula or for overshoot etc. If yes then what is it ?
So what is going to be steady...
And how do I find rise time etc for a TF of the form \frac{K_iS}{(1000+K_i)s + 50} ? Even if I divide it I still can't get to solve it to get the risetime etc using the formulae for 1st order systems because a constant term comes..what should I do with it ?
