Pull strength

Pull strength

Pull strength

(OP)
Gents,
Can pullout strength (e.g. of an insert or bolt)of composite be determined by analysis??

RE: Pull strength

Only as a very crude approximation: use a conservative interlaminar shear strength times an assumed effective area.  Testing is recommended.

RE: Pull strength

(OP)
Thanks SWC,

Question, don't the fibre strength and thickness of the laminate play any part in the pullout strength

RE: Pull strength

Yes, but pull-thru strength is a very complicated mix of failure modes.  Have tried to correlate several analyses with data without much success, unless one is very conservative with assumptions.

RE: Pull strength

Normal load can be applied to surface and then check material permissible stresses and strains. Do you have glass fibers or carbon fibers?

RE: Pull strength

ameyad - have you correlated your method to test data? or is it just theoretical?

RE: Pull strength

(OP)
ameyard,
the fibres are carbon fibre in fabric and UD form. Could you be more specific with regards to the material permissible stresses and strains
