    Axisymmetric model : Deflection discrepancy with standard formula

    Hey, thanks a bunch. That actually worked, trying fully integrated elements. Also, changed the constraints a bit. Thanks again :)

    Axisymmetric model : Deflection discrepancy with standard formula

    Sorry, ignore that question :). That was dumb actually. Yeah, but the ABAQUS deflections are different from the actual values. I can't understand the source of the error. I input the load for the axisymmetric model as the entire Load i.e. Load per unit length multiplied by the circumference on...

    Axisymmetric model : Deflection discrepancy with standard formula

    Yeah, I get the same results using ABAQUS, but those are the unscaled values. When I query the node at the inner radius, I get scaled and unscaled values of deflection. Now, do I multiply the unscaled value by the scale to get the actual displacement? Or is the unscaled value the correct answer?

    Axisymmetric model : Deflection discrepancy with standard formula

    Hey, I think turning nlgeom on has solved most of the discrepancy. However, the ABAQUS value is nearly half the calculated value (from the closed form solution). This error seems to be consistent for different variations of the model. Any ideas why?

    Axisymmetric model : Deflection discrepancy with standard formula

    Hi Xerf, Thank you for replying. I actually meant it's the height of the section, not the thickness. I'm pretty sure abt the consistency of the units. I played around with the model a bit - I realized that I had ramped the load linearly over the step when I had to put an instantaneous force. I...

    Axisymmetric model : Deflection discrepancy with standard formula

    Hey guys, I can't seem to figure out where I'm going wrong. I analyzed an axisymmetric model subject to a uniform load along a circumference and compared the resultant deflection with the textbook closed form solution, but there's a huge difference. The modeling seems simple enough! The disk...
