Interim report: Compendium of material test results on HY-100 and pseudo HY-100 metals in support of United States Navy programs.

摘要

This report documents the status of ongoing tests performed to construct a material database for use in structural analysis codes. Room temperature uniaxial tension and compression tests were performed to quantify isotropy and strain-rate sensitivity at static rates. Notched tensile tests were performed to support development of the damage portion of coupled flow-damage constitutive models. Plate perforation tests were also performed to be compared with future analytical predictions. Limited quantities of the pseudo HY-100 material permitted only a subset of such tests. Future tests are to include high-rate compression for improved strain-rate sensitivity modeling at anticipated service conditions, and elevated temperature compression testing for improved modeling of potential material softening due to adiabatic heating. 3 refs., 11 figs.
