Can Acad calculate the forces an object can withstand given dimensions and materials?

Hello!

I am designing wing ribs for a prototype, ribs made with fir wood; I must make cuts in the ribs in the form of circles or triangles to reduce the weight but keep the strength. I think I will use circles because a triangle's corners can be starting points for fissures(maybe triangles with rounded corners?).

Given: wood type,fiber alignment, rib dimensions, pattern of circles and circles' diameters,

can Autocad calculate the forces that rib can withstand on each axis ox,oy,oz?

Is there another program that can tell me what forces an object can withstand given information about that object?

Thank you!

No, AutoCAD cannot do that.

do you know of a program which can do that?

Perhaps Inventor but I can't say for sure since I don't use the program. You'll have to wait for someone who does use it to comment further.

ok.Thank you!

Is this what you had in mind?

wow, this is EXACTLY what I had in mind!

ReMark, Thank you very,very much!

PS: I wonder if it can simulate air flow patterns on shapes and resulting drag/lift forces...

I can do magic but I can't perform miracles. LoL I have no idea if Inventor can simulate air flow patterns.

Solidworks Flow Simulation Software might be what you are looking for.

Yes,it seems to be! you have been an immense help, ReMark, thank you!

There is a huge amount of learning ahead: Solidworks Flow Simulation Software and Autodesk Inventor

but the possibilities these two programs unleash are worth the struggle.

Thank you again!

You're entirely welcomed but don't trust to my advice. Wait for the experts to get here and add their comments.
