Its a one off production. I think the plan will be to test and substantiate based on material strengths and to demonstrate on a sample system that the whole shear assembly works. I've been pointed in the direction of the Air force method for assessing the bending stress. Essentially...

Thanks for the input Ed. We are waiting on these to be tested. Essentially, the piston actuates a swing arm, we need the system to fail when applying a load to lift the unit out of a restricted hole without overloading the hoist. the manuf wants to use a weld rod alloy which as you can guess...

Desert Fox - Good spot - The drawing i was given wasn't finished. The actual fits both appear to be G6H7. For my initial draft i took account of this and suggested that it would be a case of pure shear. I was asked to account for localized deformations close to the edge interface.

Hello, I'm facing a problem trying to assess a shear pin design. The design is made by a third party so we have limited influence but have been asked to ensure the design is fit for purpose. The design is for a circa - 2mm pin which attaches a 33mm OD pneumatic piston to a 8mm OD piston...
