Subject: Failure model for a metal bellows
Message:
Hi I am trying to find a failure rate model similar to other mechanical models in the Carderock mechanical reliability handbook. I realize that NPRD-95 has a couple of data points for bellows but they are GF environment (ours is naval unsheltered) and the failure rate is given independent of number of cycles, material, etc. I would expect those parameters to play a large part in the failure of a bellows. Thanks for your time. Bob Valerius 410-260-5247 410-694-2387 fax
