Diametric Disc and Standard Tensile-Test Correlation Study. Process Development Endeavor No. 209

摘要

The tensile and diametric disc ultimate stress-strain group means of fifteen lots of RX-03-BB material were used to determine the correlation between the standard tensile test and diametric disc test. Statistical results show that the tensile/disc ultimate stress linear correlation coefficient was high (0.879) and the linear correlation coefficient for strain somewhat lower (0.568). Density variations as low as 0.020 Mg/m exp 3 significantly affected the diametric disc ultimate stress. The ultimate strain was not significantly affected within the limited density range (0.055 Mg/m exp 3 ) of this experiment. (ERA citation 06:019172)
