Hej,

how is it possible to determine the average stress over a area/plane (e.g. yellow/black line in image below) in simulation results? Is that possible with solidworks?

Background: in this study different joints are researched. The average shear in the plane yellow/plane or the average tensile stress in the neck are important for the design evaluation.

Ciao F

Ps.: I hope that the right technical terms for this case were used.

Also helpful is to:

break = cut the model using one of the tools in solidworks like split

Correct Answer

You'll need to use split lines to define up the line/area you want to average over (if it doesn't already exist). You can then define a sensor to calculate the average or RMS of a stress quantity over the selected entities.

Hej Shaun,

thank you. What you have described works quite well. Do you know a other way to achieve such results without defining several solids, because to define all component contact conditions takes quite some time?

Best regards

I'm not entirely clear on what you're asking for; are you asking if you can divide a solid body up into multiple bodies instead of create multiple parts and putting them in an assembly?

No. I wanted to know, if there is a way to research stresses on lines in my assembly more effect?

And if not how would you do it with split lines tool if you have to evaluate multiple planes in a part of a assembly (like the blue lines in the image below)? [subquestions: Do you make a sketch for each line? How do define the contact conditions for the part in the assembly...]

I hope my intentions with the earlier question is now better to understand.

lines is the exact same thing as faces

break the body into multiple bodies so there are body edges or use split lines

contact just apply the same way, bonded. you're just breaking the model up to make it possible to measure on specific things.

What about a section view, use prove to grab a decent sample of points and then do the average yourself or use there data in the dialog.

If you want more exact, you need to define the break so that it can be selected.

Hej Jared,

What are breaks and how will that leed me to evaluation of shear stress in a plane?

I am looking for a more precise and automatic approach to get shear stress values in a plane, because those informations should be used for a dseign evaluation.

Thank you
