Fracture in A356 T6 alloy
Fracture in A356 T6 alloy
(OP)
Our customer returned a casting fractured in the field.
Very close to the fracture, there is a dent.
Is there any way to determine the impact load base on the dent dimensions (area and depth)?.
The part is made in A356 T6 aluminum alloy.
Any comments or leads we will appreciate.

Depth*area*Ultimate_strengrh = energy

Different temperature may give different fracture load..

the casting was returned to me with a clear fracture along this radius and 13 or 14 crescant dents along the face. after investigation and talking to the customer manager. I found out that it failed because it was attacked with a 5 lb hammer repeatedly until it broke.
Suffice to say i was not amused.
p.s the reason it was assaullted was to see how long it would be before it broke......it passed....

Your comments and answer helped to find the root cause.
Thanks

A clear Cause-Effect diagram would lead you to the correct cause and thereafter to the solution.
