Microspalling Process of an Explosively-Driven Metal Tin: Experiments and Numerical Simulations

Microspalling Process of an Explosively-Driven Metal Tin: Experiments and Numerical Simulations

Shock-induced melting phenomenon in tin material attracts considerable attention recently. Particularly, under the strong explosively loading, the shock-induced melted tin with lower strength is the weak region where the dynamic damage and fracture commonly appear, resulting in the “micro-spallation...
