Sudden Impact Loads
Sudden Impact Loads
(OP)
I have a component that is a 20mm diameter pin with a necked section of diameter 11mm. This component is design to fail when there is an excessive force within the machine.
I have carried out testing and have got a failure load for when the pin fractures.
But this load is applied gradually using an hydraulic pump. In service this load will be applied instantaneously. I think that with a instantly applied load the pin will fracture at a lower load than a gradually applied load.
Does anyone know of a factor to calculate this?

RE: Sudden Impact Loads
Brittle fracture is the exception. The occurrence of this depends on the presence and sensitive of notches.
