Stress Concentrations for Plate with Hole - Applied Bending Moment
Stress Concentrations for Plate with Hole - Applied Bending Moment
(OP)
Greetings all,
I could use some help tracking down a extensive chart showing stress concentrations for plates with a central hole for the case of an applied bending moment.
Additionally, any commentary or tips on the problem of designing a padeye to sustain a force applied at an angle to the plane of the padeye would be helpful. I believe I can simply resolve the applied force into the tensile portion and the bending portion and use the stress concentration charts to find the design stresses?
Also, I have found that 5 times the U.L. is the OSHA requirement for padeyes. Is anyone aware of other relevant regulations on padeye design/safety?
Thanks in advance for any tips and help on these matters,
Mike

If you can tap holes in the product, use swivel hoist rings [the greatest invention!! they always align so there's no "weak " direction http://www.americandrillbushing.com/ogn_hoi2.htm ]
also, pad eyes usually have no "official" rating, since a lot depends on weld quality/workmanship. http://www.thecrosbygroup.com/Crosby/
For Stress Concentration Factors, is there anything better than Peterson's book? [probably not]

in this case, a swivel hoist is not practical, but i will certainly keep this technology in mind.
additionally, could you please give me the title of Peterson's book? I am unfamiliar with this work.
Thank you,
Mike

chicopee:
We use commercial lifting supplies from Crosby, however the steel department at the shipyard manufactures their own padeyes for the riggers.
Thanks,
