Lambert-jonas equation is used to fit the experimental results into a curve. The effect of quenching on ballistic behavior of HSLA-100 is also studied. The experiments are conducted on 3mm thick rectangular specimens impacted by blunt tip projectiles. The results indicate that for the as-received material, the ballistic limit is nearly the same for ambient and -400°C temperatures, but increases significantly by 30% and 40% for -800°C and -1960°C temperatures, respectively. The same trend is observed for the quenched specimens. However, the increase of ballistic limit is lower for the quenched specimens and is 16% and 30% for -800°C and -1960°C temperatures, respectively. The ballistic test was also simulated using Ls-dyna hydrocode to examine the effect of parameters such as the specimen’s thickness, the projectile’s tip shape and mass on the ballistic limit of the materials.}, keywords = {HSLA,100,Ballistic limit,Sub,zero temperature,Lambert,Jonas,Residual velocity}, url = {https://www.ije.ir/article_72849.html}, eprint = {https://www.ije.ir/article_72849_63dea6733188a4da995e896eed59a973.pdf} }
