Study of Hypervelocity Projectile Impact on Thick Metal Plates

AbstractIntroductionMaterials and MethodsExperimental ResultsNumerical SimulationsConclusionAcknowledgmentsHypervelocity impacts generate extreme pressure and shock waves in impacted targets that undergo severe localized deformation within a few microseconds.These impact experiments pose unique challenges in terms of obtaining accurate measurements.Similarly,simulating these experiments is not straightforward.This study proposed an approach to experimentally measure the velocity of the back surface of an A36 steel plate impacted by a projectile.All experiments used a combination of a two-staSee more on hindawiSteel Strength vs Steel StrengthWe might then say that this strength-equivalent one and a half inch thick aluminum plate will yield at around 51k per square inch of surface area (around 29% greater yield strength than the equivalent region of steel plate),and will fail at around 67.5k psi (around 12.5% greater ultimate strength than the equivalent region of steel plate).TESTING OF M203x9.7 (M8x6.5) AND S76x8.5 (S3x5.7)(M8x6.5) steel post was able to dissipate more energy than the S76x8.5 (S3x5.7) steel post with soil plate attached.Based on the results presented herein,the M203x9.7 (M8x6.5) with a 106.68 cm (42 in.) embedment depth should be considered for new cable guardrail systems.The force levels and energy absorbed at an embedmentTechnical Bulletin May - MCAA3 1/2 352 504 34 67 89 4 327 473 36 63 84 5 287 423 42 54 72 6 261 409 48 47 63 8 229 362 .If the hydrostatic test pressure is greater than shown above and you can heat the fluid used during hydrostatic testing above 90°F,no further action is necessary.If that is not possible,when ordering the following materials:
