    Ice axe supported on tape - loads and boundary conditions

    Of course in this picture it's not an ice axe becouse I don't have one. I just show the way how it's supported.

    Ice axe supported on tape - loads and boundary conditions

    Number 1 in fig.1 is tape (it's tape used in mountaineering but it doesn't matter) so there aren't any welds. Just ice axe hanging on tapes with force applied also by tape. I attached photo which shows how it looks like more or...

    Ice axe supported on tape - loads and boundary conditions

    I'm not sure if I get everything you wrote (I'm not native English speaker so I may not understood this correctly) but in response to 1. - fig.1 just shows method of testing ice axes. My model has flat bottom. And in response to 2. (this is the part which I could misunderstood) there aren't any...

    Ice axe supported on tape - loads and boundary conditions

    I was considering bearing load but I can only apply this to cylindrical faces and in my model part of those surfaces are flat so I have no idea how to apply this force. And what you think about restraints in the supports?

    Ice axe supported on tape - loads and boundary conditions

    Could anybody help? If I did't present my problem clearly enough just let me know.

    Ice axe supported on tape - loads and boundary conditions

    I'm analysing ice axe according to standard. It is supported on some kind of tapes and force is also applied by this tape (fig. 1). I'm not sure what restraints to use and how to apply it. I created surfaces 15mm width (width of tapes according to standard) on half of shaft (for both supports...

    Heat transfer between I beam and environment

    Units are meters, Newtons, Pascals. And I defined material with Elastic Modulus = 2.1E+011, Poisson Ratio = 0.3 and Thermal Expanssion Coefficient = 1.2E-005

    Heat transfer between I beam and environment

    I changed my assumptions a little. Now instead of analyzing just I beam I'm analyzing gantry crane and I've got a question. Is it possible that for 50 degC displacement are smaller than for -30 degC? I've done just structural analysis with temperature as one of loads like corus said. It was...

    Heat transfer between I beam and environment

    There is no heat source. Just I beam in the open air. And for now I'm interested in steady state analysis. So what BC I should exactly create in Patran? Should I choose convection with option: To Ambient and just define ambient temperature? Sorry if I don't get some obvious thing that you wrote...

    Heat transfer between I beam and environment

    Hi, I've got a question about heat transfer. I'm doing thermal-structural analysis in Patran and I'm not sure what boundary conditions I should use in thermal analysis. I want to analyze displacements in I beam in different ambient temperature. Should I define convection or radiation in this...
