adhesive shear allowable under torque
adhesive shear allowable under torque
(OP)
I'm having trouble thinking about how to come up with a ballpark allowable value for a bonded attachment under a torque load.
The attachment pad is circular and is bonded to a baseplate. The pad has a direct shear allowable of say 100lb. However, it is subjected to a force which will induce a rotation about the base giving rise to torque-shear in the adhesive.
Any ideas?

Also note that failure of the "test" article may not have been in the elastic region, so your answer may be off as well.
When in doubt, install some fasteners through that puppy :)
