1D PBEAM von Mises stress

Recommended Posts

Hello,

 

i am trying to calculate von Mises stress for a beam. The beam has a weird cross section and i already defined the section in hyperbeam. for properties i use PBEAM, since there is no cross section that is the same in optisctruct library. i have gave the value for continuation line 2, 5 and 6. in Output, i have requested stress for all type. There is no problem during the calculation and in the result type(Hyperview), it only shows Displacement, Element strain(1D) and Element stress(1D). Under Stress, i can only choose axial and long. stress, but i need von Mises Stress.

How can i obtain the von MIses stress?

 

thanks in advance

i have use other method.. which is:

i use the displacement produce due to the force applied on the 1d model, and apply it in a 3d model which have the biggest deformation from the 1d model

Hi 

 

I´m not sure if this is what you need but in the .res file, you can find the "Abs. Max. Principal Stress" for the CBEAMs. 

You only need to load the .res file instead of the .h3d file in hyperview. Before that, you need to set the 4 points (C,D,E,F) of the cross section that you want to evaluate.
