FEA on hollow sphere

Tan Jxvenger Nov 17, 2016 10:00 AM

Hi all! I'm still learning how to use solidwork and is wondering how do I do a FEA on a hollow sphere without flat surfaces. And also how do I obtain fibreglass material as it doesnt have a complete information on the material list. Thanks in advance! Problems: FEA requires a fixed fixture thats why

What are you trying to "do" to the ball? You can fix a point if there is one on the surface. You can used Advanced to fix cylindrical surfaces.

  Thanks for the speedy response! I'm trying to make a sphere capsule, making it able to withstand certain force when applied. But the result I kept getting looks really bad...

    What forces? How and where are you applying them? If you've split the surface then you've got edges/points you could fix. Got a picture?

      Pardon me, I know it looks really bad. I'm relatively new to this and there isnt any tutorial for sphere FEA. The material I'm using is Alloy steel for now. I trying to simulate in reality when debris falls on the capsule, it can withstand the force hence prolonging the survivors inside it.

        I can't tell what all your forces are but could you assume the base of those 3 'posts' are fixed for starters?
