This investigation focuses on modelling the fracture zone of four materials at different test speeds. The influence of these test speeds on the fracture zone formula was investigated as well. The fracture behaviour of materials is an important parameter which greatly affects the performance of these materials. In this paper, an empirical formula was generated to predict the fracture zone. This formula was produced from experimental characterisation of the fracture process at different loading rates for some engineering materials. Statistical analysis was done for the results being obtained from the experimental work to verify the accuracy of this formula, and it was found that i t can introduce an accurate base for fracture zone prediction and determination. It was noted that at fracture process initiation, there are no significant effects of varying loading rate; this effect is increased with increasing the fracture process propagation.
