    Von Mises result analysis help

    Phill Zaza

      Hello i have make 2 von Mises tress analisis

       

      First picture:full structure

      Second picture:one i remouved 2 main T profile bar

      thrid picture: Original struture

       

      on the second picture the plate disepear

      the yield stress point at 195000000 went on green mark on the second one (the weak one)

      How can i "validate" the struture , is the von mise Max (on the scale) have to be my yield strenght

       

      also, is that normal that my T profile ,when meshed went round, and not present on the result

      I have try with other imported T profile, everything was looking normal

       

      Why it is writen Default as machined

      any good site to found more info on analisys

       

      i did write Von Mises analysis because it was the default one

      any other analysis is good to have a look for this kind of struture

       

      yes a lot a question, i am starting...

       

      thank you in advance

          Hi Phill, I am no expert but will give it a shot to answer your questions.

           

          on the second picture the plate disepear

          the yield stress point at 195000000 went on green mark on the second one (the weak one)

          From your Picture 1 the maximum Von Mises stress in the structure is 258194960 N/m^2 while the Yield Strength is 195 000 000. So basically the arrow is pointing to the material yield strength, So you must check where this max stress is occuring in the part, some times it is at sharp Corners (stress concentration) before you can conclude if the structure will fail in this case.

           

           

          also, is that normal that my T profile ,when meshed went round, and not present on the result

          I have try with other imported T profile, everything was looking normal

          T Profile goes round because SW Simulation automatically treats Strucutral members as "Beam Elements" and so they go round, If you "treat" this as "Solid" it will retain it's original shape.

           

          Default machined thing is coming from your model because this is a welded part it has two configurations "As Welded" and "As Machined"

           

          Please look in the help section to understand better on each of the Point.

           

          Good luck.
