The velocity of the projectile before and after perforation, the diameter of the front face deformation, the depth of the crater and the diameter of the hole were measured. The fracture surfaces of the plates near the ballistic limit were also microscopically analyzed. The highest ballistic limit was found in 2 mm-thick plate (332 m s(-1)) and the lowest in 1 mm-thick plate (97 m s(-1)). While, the ballistic limit of 2 x 1 mm-thick plate decreased to 306 m s(-1). Typical failure mechanism of the projectile was the flattening and mushrooming at relatively low velocities and the separation from the jacket at relatively high velocities. In accord with the ballistic limits, 2 mm-thick target plate exhibited the highest hardness value. Microscopic investigations showed the significant reductions in the grain size of the targets after the test.eninfo:eu-repo/semantics/openAccessMaterials scienceImpact and ballisticFilm and sheetFailure analysisSteel platesPerforationTargetsProjectileResistanceBehaviorStruckMetal claddingProjectilesQuality assuranceSheet metalBallistic impactBallistic limitBallistic performanceBefore and afterCold-rolled sheet metalExperimental investigationsFailure mechanismFilm and sheetFracture surfacesFront faceGrain sizeHardness valuesHigh velocityImpact and ballisticLow velocitiesThick plateThick targetFailure analysisArticle0002869042000332-s2.0-7864990559413561366323Materials science, multidisciplinaryProjectiles; Armor; Gas Guns
