Charpy test
  • materjali sitkuse määramine Charpy meetodil, mille korral sälguga või sälguta horisontaalselt kahele toele paigutatud teimikule rakendatakse löökkoormus (vt löökpaindekatse; vrd Izod löökpaindekatse)
  • a flexed beam, notched-specimen impact test in which both ends of notched specimen are supported and a stricker carried on a pendulum impacts the specimen centrally on the face opposite the notch; the energy absorbed in fracture is then calculated (see: impact bending test; compare: Izod impact test)
    Good to know
    • An impact test in which a V-notched, keyhole-notched, or U-notched specimen, supported at both ends, is struck behind the notch by a striker mounted at the lower end of a bar that can swing as a pendulum.

Charpy V-notch test
  • standarditud pingetaluvuse katse, mis määrab katsekeha poolt murdumise ajal neeldunud energia koguse, kusjuures see imenduv energia on katsekeha sälgu sitkuse kaudne mõõtesuurus
  • löökpaindeteim, mille korral sälguga või sälguta horisontaalselt kahele toele paigutatud katsekehale rakendatakse löökkoormus
  • standardized high strain rate test which determines the amount of energy absorbed by a material during fracture, and absorbed energy is a measure of the material's notch toughness

Usage examples
  • Charpy löökpaindekatse oli otsustava tähtsusega laevade keremurdumiste probleemide mõistmisel Teise maailmasõja ajal
Good to know
  • Charpy löökpaindekatset kasutatakse tööstuses laialdaselt, kuna seda on lihtne ette valmistada ja läbi viia ning mõõdised on saadavad kiirelt ja odavalt, kuid puuduseks on see, et mõned tulemused/mõõdised on ainult võrreldavad.

Usage examples
  • Charpy impact test was pivotal in understanding the fracture problems of ships during World War II.
Good to know
  • Charpy impact test used in industry, since it is easy to prepare and conduct and results can be obtained quickly and cheaply; a disadvantage is that some results are only comparative.
