Hi all, How to find the plasticity reduction factor for crippling stress. I have seen such factors only available for Buckling stress in Bruhn C5.7 or C5.8 and the same in Niu. Can anyone suggest a way forward for crippling stress?
And which method is efficient to find the crippling stress of...
Can anybody tell me the shear strength of the NAS1669 Jo-Bolt fastener? I checked in the fastener specification I am not getting the value and I have gone through MMPDS-09 also. Nowhere I am to find the shear strength value.
It is not about a thinner part or thicker part edge distance. The issue is which part is having lowest bearing allowable value as per design and which part is affected in your NCR. Need to re-evaluate the NCR bearing allowable value with the reported edge distance and check it is far above the...
HI SWComposite, My issue is with a single part only. Not a joint. The issue here is during the assembly process, the operator has done the wrong countersink on the other side of the part. now we need to correct with doing countersink as per design and thinking of producing the csk filler on the...
Hi all,
Did anyone come across the usage of CSK filler in repair? If yes can we use it in both sides on a single part providing enough thickness on the part?
As for my knowledge, Stringer profiles are selected based on the failure mode and stress to be withstood when it is attached to the skin. And in more the cross-section area of the stringer plays a major role in the design stage. Based on FEA extracted stress acting on the particular area, and...
