  • tahke keha kuju ja/või mõõtmete muutus (vrd moone)
    Good to know
    • Kirjeldab geomeetrilist muutust ennast, käsitletuna kas muutuse protsessi või selle tulemust. Deformatsiooni võib liigitada mitmesuguste kriteeriumide alusel, sealhulgas deformatsiooni viisi (nt tõmbe-, surve-, nihke- või mahuline deformatsioon) ja taastuvuse järgi (nt elastne, plastne või anelastne deformatsioon). Need liigitused täiendavad üksteist: konkreetset deformatsiooni võib kirjeldada rohkem kui ühe kriteeriumi alusel.
  • change in shape and/or size of a solid body (compare: strain)
    Good to know
    • Describes the geometrical change itself, whether considered as a process or its result. Deformation may be classified according to various criteria, including deformation mode (e.g. tensile, compressive, shear, or volumetric deformation) and recoverability (e.g. elastic, plastic, or anelastic deformation). These classifications are complementary: a particular deformation may be described using more then one criterion.

  • algmõõtepikkuse (Lo) suurenemine mistahes katse momendil (vt protsentuaalne pikenemine, suhteline pikenemine)
  • increase in the original gauge length at any moment during the test (see: percentage elongation, egineering strain at fracture)
    Good to know
    • The increase in length of a specimen during the tensile test is calculated as (Lo - Le), where Lo is original gauge length, Le - extensometer gauge length.
