The subsequent spall failure propagated via cavitation events that involved the nucleation of nano-and micrometer-sized voids with very limited plastic growth. Post-test fractographic analysis of the shock-recovered specimens suggests that the initiation of spall was most likely associated with intermetallic Al 2 Ca-bearing precipitates forming during the hot extrusion process. The experimental data also revealed some inherent scatter in the spall strength data due to microstructural heterogeneity. The spall strengths extracted from the free surface velocity profiles of the shocked specimens was found to increase by 8% for shock stresses ranging from 1.61 to 4.53 GPa. The Hugoniot Elastic Limit (HEL) was measured to be approximately 187 ± 11 MPa. Regarding simulation of fracture in the Taylor bar impact tests, the work. Incipient spall damage in the specimens was measured at different shock conditions using 51 mm and 105 mm diameter bore gas guns. Failure modelling in numerical simulations of ballistic impact problems has. A study contrasting the performance of the SVM and LDA classification technique in the context of the decision-making process based on power spectrum density. A B S T R A C T Normal plate impact experiments were conducted to study the spall behavior of AMX602 magnesium alloy fabricated via Spinning Water Atomization Process (SWAP), which was followed by cold compaction and hot extrusion.
