Reverse Loading Effects in Bend Tests on Hot Isostatically Pressed (HIP) Beryllium.

Abstract

Results of four-point bend tests on two grades of hot isostatically pressed (HIP) beryllium are presented. Both one-directional and reversed loading were used to evaluate the effects of precompression on the subsequent tensile strain to failure. Additional tests on wide-bend specimens were used to evaluate the response of beryllium in bending under plane strain conditions. Stress-strain curves calculated from the results of bend tests indicate that flow stresses are higher than those obtained from uniaxial tension tests. (Author)
