Research on explosive forming of magnesium alloy plate using numerical simulation and experimental studies (I)

This study investigated the metal forming of magnesium alloy plate using an intense dynamic loading called as explosive forming. Normally, magnesium alloys have an advantage in terms of strength-to-weight ratio, but it is difficult to perform cold-metalworking through regular metal forming methods. Therefore, explosive forming, which is one of the metal forming techniques with a specific forming mechanism, is employed. The experimantal study is made for AZ31 magnesium alloy plate as to obtain the optimal experimental conditions. It is also performed numerical simulations to estimate the formation of wrinkles and cracks which matches the experimental results.
