Re: Thick and Thin shell Definition
i think it is a common definition
thin shell is for where bending is predominant and shear is negligible
thick when either of those isn't true
the best place to get more info is the solidworks knowledgebase at customerportal.solidworks.com

Re: Thick and Thin shell Definition
the help also provides this more general suggestion:
In general use thin shells when the thickness-to-span ratio is less than 0.05.

Re: Thick and Thin shell Definition
Thanks for your Suggestion Jared. I have actually seen the help for this but I was still confised because in shell definition software asks us to define the thickness for the shell and then u have to choose between thin or thick instead of software taking it automatically. So let me Rephrase my question.What are the criterias in making a decision whether the shell is thin or thick?
The informatuion u provided in the first Reply is aslo useful...
Thanks again....

Re: Thick and Thin shell Definition
General guidelines .....
- If span/thickness is less than 10 use solids
- If Span/thickness is between 10 & 20 use thick shell.
- If span/thickness greater than 10 use thin shell.

Re: Thick and Thin shell Definition
the value of the thickness has nothing to do with the formulation that is used.
the formulation that is used is either thick or thin.
you choose based on the guidelines that bill provied. but on the back end, you choose thin if bending is predominant and shear across the thickness is negligible.
