Title CHAP8 Author Administrator Created Date 9/6/1999 12:47:51 AMCharpy Impact Test - an overview ScienceDirect TopicsThe standard Charpy impact test specimen is of dimension 55 mm × 10 mm × 10 mm,having a notch machined across one of the larger dimensions,as illustrated in Fig.1.3.The Charpy impact test measures the energy absorbed by a standard notched specimen while breaking under an impact load .This test consists of striking a suitable specimen with a hammer on a pendulum arm while theCommon Methods of Testing Steel Material Charpy V-Notch Test for Toughness.The Charpy V-Notch test -- or Charpy Impact Test -- measures a material's ability to absorb energy,or impact,within a given temperature range.The test gets its name from Georges Charpy,who first standardized impact testing.
The Charpy specimen is relatively easy to make and test.A precise V notch is placed in the bar.This can be ground or broached.The Charpy specimen is placed in a fixture such that the ends are held against a stop.A weight on a pendulum is raised.For example a 50 pound weight can be raised 3 feet (height h1 in sketch.)FATIGUE RESISTANCE OF HIGH PERFORMANCE STEELFigure 4-12 Charpy V-Notch Energy versus Temperature for HPS 485W and 350WT Steels..92 Figure 4-13 Comparison of Charpy V-Notch Energy versus Temperature between Side Specimens and Middle Specimens from the 51 mm HPS 485WFile Size 460KBPage Count 10steelwise - AISCgrades like ASTM A529 Grade 50,ASTM A572 Grade 50,or fined standard for Charpy V-notch material toughness.The availability and cost-effec- Gr.lak,lb II 50g 70g Gr.III 50 65 50 50 65 A709 50S 5065 65 50W 50 70 50 50h 65h A913 60 60 75 65 65 80 70 70 90 A992 50i 65i
