Crack resistance determination from the charpy impact test

Abstract

Many engineers and scientists investigated the possibility to correlate Charpy impact energy with the fracture toughness. As a result, many empirical correlations can be found in literature [1–2]. However, most of these correlations had a limited application range due primarily to their empirical basis. Recently, a simple procedure was provided to determine crack length from the load-displacement test record [3]. The basic idea is that crack length is proportional to the absorbed energy, namely: ∆a_i ∞(E_i - E₀/E_final - E₀)²((1)) where “Ei” is the absorbed energy at time “i”, E₀ is a threshold energy corresponding to onset of crack extension and E_final is the final energy corresponding to a measured crack extension Δa_final.
