I'm having problem to define the bilinear elastic-plastic material. I have the following information.
density = 7800 kg/m^3
Young Modulus = 193 GPa
Yield strength = 207 MPa
Poisson's ratio = 0.27
Tangent Modulus = 692 MPa
Shear Modulus = 75 MPa
I already ran the first simulation, but the...
I know there are lots of factors come into play when determine the bending stiffness. I am more concerned about the material and the design.
I'm using high carbon steel as the material. The density is 7490kg/m^3, Young Modulus=198000 MPa, and Poission's ratio=0.29.
I modeled the frames of...
I don't really get this.
I have a balloon and stent, and I need to apply an internal pressure on the inner surface of balloon. The balloon will expand, then the stent will expand as well.
However, when I review work done by other, I came up with this statement.
"As illustrated in Fig. 2...
So far I have search, the reason for failure of stent does not come from blood flow in artery. The most common reason is the fatigue failure, due to the cyclic loadings of the of the pulsatile blood pressure (solid mechanics point of view).
I want to know if the from the fluid mechanics point...
I have a hollow cylindrical object. I want to apply a pressure acting on the inner cylinder wall, which is circle in geometry of course. Then I would like to view the expansion of the cylinder object, due to the pressure acting on it. Please refer to the link, under the post of flash3780. The...
Please refer to the link under attachment, that's my model (using Solidworks). This is regarding my final year project. Load analysis on stent.
I want to apply a radial load onto the inner surface of the balloon, so that the balloon will expand, which in turn will expand my stent.
I'm using...
Can I model it using line element, beam element, or plate element?
So this is my final year project. I have to do analysis on the load distribution of the coronary stent. I need to make sure which element will give the most accurate result.
If I import the CAD model from Solidworks, which...

Why I cannot display the value of dimension in my sketching? You can clearly see that my vertical dimension is 16.25 in, and my horizontal dimension is 7.07 in, but the values in the sketching is weird?
And the triad is supposed to be X, Y...
the value of yield strength/design load is equal to the safety factor given. Is it safe or yield?
I need to consider the weight of the whole structure as well. If i use bigger dimension, it is of course more safer, but the weight will increase as well.
So, can the safety factor calculated...
In FEMAP, i obtain the max stress of Bar EndA and Bar EndB. Then from there i calculate the von mises stress using the von mises yield equation, (σa)^2 - (σa)(σb) + (σb)^2 = (σv)^2
where σv = von mises stress
Let's say after my analysis, I get σv = 208MPa
Given the yield strength is 210MPa...
