| Abstract: | A simple, self-aligning, uniaxial test firtiire has been developed for testing ceramics. The primary emphasis is placed on a simple specimen geometry and test procedure. The strain gage measurements on α-Sic and steel specimens indicate very good uniformity in the tensile stresses (with variation less than 1%) across the cross section. The tensile testing of SiC and SiC/TiB2 composites exhibits 55% and 79% failures, respectively, in the gage section with possible further improvements. Average tensile strength values of 160 and 202 MPa were obtained for α-SiC and SiC/TiB2 respectively. |
