WRDC-TR-89-4123, TECHNICAL REPORT: REVIEW OF THE MIL-HDBK-5 PROGRAM (DEC-1989)

WRDC-TR-89-4123, TECHNICAL REPORT: REVIEW OF THE MIL-HDBK-5 PROGRAM (DEC-1989)., A summary of the technical accomplishments for the MIL-HDBK-5 Program is presented. Design values (minimum tensile yield and ultimate, compressive yield, shear ultimate, as well as bearing yield and ultimate strengths) for new products, such as, 2090-1783 sheet, 2519-T87 plate, 6013-T6 sheet, 7150-T6151 and T7751 plate, 7150-T61511 and T77511 extru- sion, Ti-15V-3Cr-3A1-3Sn sheet, and Ti-1OV-2Fe-3A1 die forgings, were incorporated into MIL-HDBK-5. Design values for many products in the document were revised due to reanaly- sis according to current guideline procedares, and/o- the availability of additional data. Some design allowables were modified because of specification changes in specification limits so as to achieve compatibility with reference material specifications. Design values for a considerable number of products were upgraded from S basis to A and B basis. Elevated temperature data for various mechanical and physical properties of certain mate- rials were added or revised. Fatigue data in the form of S/N or e/N curves were included for many materials. Joint design allowables for various fastener systems were added to MIL-HDBK-5. Improved statistical analysis procedures, as well as analytic techniques for analyzing strain control fatigue data, were incorporated. The procedure for analyzing load control data was revised. The Handbook was revised annually incorporating the above-described changes and additions. Four change notice revisions and one complete reissue were published.
