Static and dynamic bending tests of U-notched specimen of ferritic spheroidal graphite cast iron were interrupted in crack propagation stage and the ligament width of the specimen was measured. Crack propagation energy varies with ligament width in parabolic relation, and critical stress intensity factor remains unchanged during crack propagation. Bending load and energy in dynamic tests are larger than those in static, and the strain hardening exponent varies conversely. In order to study the effects of deflection rate on the bending load more precisely, the static bending rate was altered repeatedly in the crack initiation and propagation stages. Based on the experimental results, bending load was decomposed into two, rate dependent and independent, to clarify the influence of deflection rate on bending load and energy, as well as strain hardening exponent.
