mehaaniline teim/katse, mille korral koormus rakendatakse suurtel kiirustel paindel (vt löökteim, Charpy löökpaindeteim, Izod löökpaindeteim), a dynamic bending test to determine the behavior of materials when subjected to high rates of loading; the quantity measured is the energy absorbed in breaking the specimen by a single blow (see: impact test, Charpy impact test, Izod impact test), löökpaindekatse abil mõõdetakse materjali sitkus, mille järgi hinnatakse materjali kalduvust haprale purunemisele, Charpy impact bend test, also known as the Charpy V-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture, löökpaindekatse, tuntud ka kui Charpy V-soone katse, on standarditud katse, mille abil mõõdetakse summaarne materjalis neeldunud energia teimiku murdumisel
