Abstract

The effects of specimen inertia on the instrumented impact testing of cementitious composites are discussed and a method for reducing such effects is proposed. A two degree of freedom model capable of predicting the amplitude and period of inertial loading oscillations on the tup-load versus time-trace is presented. Results of tests conducted on asbestos cement and fiber-reinforced concrete are presented and are compared with those predicted using the analytical model. It is concluded that the model developed is satisfactory in predicting inertial loading effects.
