    ANSYS - Tube Bending and Measured Ovality

    Radius calculated as per the attached method. Roarks formula for circular rings (Table 9-2 if I remember correctly!) was used for the initial lateral crushing. Roarks was not used for tube bending.

    I’ll take a look at the above, thanks!

    ANSYS - Tube Bending and Measured Ovality

    Hi All, Quick background on the matter: 1. I have conducted a non-linear FEA (using ANSYS) on a super duplex stainless steel tube (Tube dimensions: 15.875mm ID and 1.00mm WT, Poisson's: 0.3, Young's Modulus = 200 GPa) representing the lateral crushing of a tube between two flat plates. 2. I...

    Force Required to Crush a Tube

    Thanks for the feedback, never heard of the kiss rule - I'll look into that. I did initially try a static loading scenario however didn't give me what I was looking for. The implicit dynamics route sounds good to me - I'll give that a try thanks.

    Force Required to Crush a Tube

    Hi Stick, Thanks for the reply! Fairly a newbie to non-linear FEA analysis myself, However thanks for pointing out the force per unit length- missed that one. that certainly brings me a bit closer. I think the asymmetrical displacements were due to my poor meshing skills - I have since...

    Force Required to Crush a Tube

    Thanks Littleinch, I'll take a look SWComposites, yes I understand - Maybe if I try with much smaller loads, the displacements may align. I'll take a look JStephen, Thanks for that reply - I'll take a look into the wide beam theory, maybe that will help me out. r6155, I am planning on testing...

    Force Required to Crush a Tube

    Thanks for the reply! however even when applying relatively low forces on the simulation (to the extent where the deformation is mainly elastic) the values still do not align. Am I missing something?

    Force Required to Crush a Tube

    I'm looking for ways in which I can calculate the displacement (vertical and horizontal) of a tube being crushed between two flat plates. I have managed to set up a non-linear material profile and simulate this problem using ANSYS however would like some sort of hand calculation to ensure I am...
