Abstract

A new technique for burst testing of low strength materials has been developed. A viscous organosilicate compound with rheopectic flow characteristics is compressed inside a hollow cylinder of the material to be tested. The compressive load is transmitted using a conventional tensile testing machine. The technique allows easy measurement of critical burst values and also intermediate values of tangential and radial stresses which provide further insight into the behavior of the test material near its bursting load.
