    Error in ANSYS

    go to solution-> solution options and select the results you want to save/append into your results file. Or alternatively, issue the outres command. You can learn about it in the help, but in your case outres,esol,all should do it. regards, Miguel Silva,Msc.

    strain concentration due to an applied concentrated transverse load

    Hello All, I would like to have a good reference about the fundamentals of strain concentration due to an applied concentrated transverse load (simple bending), or the equation to calculate it analytically. regards, Miguel Silva,MSc.

    A book that covers the topic of Stiffness of thin-walled rectangular tubes under torsion loadings

    Hi all, Thanks for all the replies, "Depending on the size and wall-thickness ratio, you may be concerned with wall buckling, and Bruhn has that, too." Sparweb, can you point the chapters where wall buckling is analyzed for torsion and for bending, if there is?? thanks, Miguel Silva

    how to calculate the torsional deflection of thin-walled beams considering buckling

    Hi all I need to calculate the torsional deflection of a thin-walled beam of arbitrary section. Thin-walled beams behave like shells, so buckling is an important factor. Is there any equation to calculate the torsional deflection of thin-walled beams taking in consideration the buckling effect...

    differences between the mechanical behaviour of solid and shell structures

    Hello All, So I am working as a R&D engineer on a company, and recently developed an analytic model for the prediction of the mechanical behaviour of complex structures. The assumptions of the model are only valid for solid structures. However, the model may be particularly interesting for...

    A book that covers the topic of Stiffness of thin-walled rectangular tubes under torsion loadings

    Hello All, I would like to know if someone can give me a good reference of a book that covers the topic of torsion of thin-walled rectangular tubes from a stiffness perspective". I have a book with the theory for non-circular hollow-sections, but that's not really much. Thanks, Miguel Silva,MSc.

    applying torsion moment on a thin-walled beam on ANSYS: a question about it

    Hello all, I want to apply a torsion moment on the nodes belonging to the transversal area of the midplane of a thin-walled beam. After following the suggestions given here: http://www.eng-tips.com/viewthread.cfm?qid=153240 I could apply the torsion moment. However, the analytical and numerical...

    expression to calculate the twist angle of hollow-box beams under torsional loads

    Hello All, I am doing some calculations, and I am calculating the torsional deflection of an internally reinforced rectangular section hollow-box beam. After looking at some websites and books, I have found that the twist angle is: T*L/(J*G), where T is the torque L is the length of the beam J...

    Stress-Strain graph

    Hi sweeney, You can still plot a stress-strain chart with different values on the x-axis. Just create a scatter chart, not the one with points, but the one with continuous line in MS excel.Just insert x and y values for compression and then x and y values for tensile and it should be fine. What...

    free older versions of ANSYS

    Hi All, I heard that there are some older versions of ANSYS that are free, like the 5.4. Is this true? Anyone knows if there is a more recent, but still free version? And can you post the link to download the free version of the software? Many thanks, Miguel Silva

    looking to start an engineering consulting firm. However got some important questions

    Hello All, I am new in this forum. I have just post-graduated in mechanical engineering. I already did an MSc. in Materials engineering. I am thinking of starting my own engineering consulting firm, however, when I think about that, some questions arise: -What are the best places to acquire...
