Quasi Static Compaction Characterization of Boron Carbide Powder

Abstract

The purpose of this investigation was to perform confined compression tests on a boron carbide (B4C) powder similar to that used to fabricate the baseline tiles used in the MEDE program. The tests were designed to measure the axial stress, hoop strains, confinement and hydrostatic pressures, and equivalent stresses within the powder material during compression. Similar tests were documented in SwRI Report 18.06188 (Ref. [1]), where the details of the procedure are reported. The provided data could be used to fit a material constitutive model such as Drucker-Prager in order to simulate the B4C powder within a hydrocode or other finite element program. Southwest Research Institute (SwRI) conducted six tests of the B4C powder (and one pretest used to assess the test setup). This report describes the materials and test methods used, the analysis of the raw data, and the results for the six tests.
