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...

| Summary: | 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” process. In the current work, three tin targets with different thicknesses are designed to investigate such micro-spallation phenomenon of shock-loaded pure tin. A new damage model considering the melting effect is proposed and the simulated results are compared with experimental measurements for the validation. |
