Proof test criteria for thin walled pressure vessels
Abstract
A proof test criterion for assuring minimum service life requirements for aerospace pressure vessels is provided. The criteria proposed are based on the results of several experimental programs conducted on surface flaw specimens fabricated from 2219 aluminum base and weld metal. A description is presented of the stable crack growth behavior of surface flaws during loading. Conclusions derived from an experimental program are discussed. It is found that significant stable crack growth under increasing load can occur prior to failure. However, significant variability in results can be anticipated even when carefully controlled laboratory procedures are employed.
