ABSTRACT
Gas gun experiments combined with velocity interferometric techniques have been used to experimentally determine the loading behavior of sleeved Cercom silicon carbide rods. Graded density materials have been used as impactors, thereby eliminating the tension states generated by the radial stress components during the loading phase. Results of these experiments demonstrate that the time-dependent stress pulse generated during impact allows an efficient transition from the initial uniaxial strain loading to a uniaxial stress state as the stress pulse propagates through the rod allowing access to intermediate loading rates. Intermediate loading rates obtained in this configuration lie between split Hopkinson bar and shock-loading techniques.
