ASTM E6-03

Standard Terminology Relating to Methods of Mechanical Testing

SCOPE
1.1 This terminology covers the principal terms relating to methods of mechanical testing of solids. The general definitions are restricted and interpreted, when necessary, to make them particularly applicable and practicable for use in standards requiring or relating to mechanical tests. These definitions are published to encourage uniformity of terminology in product specifications.
1.2 Terms relating to fatigue and fracture testing are defined in Terminology E 1823.

DISCUSSION—Ductility is usually evaluated by measuring (1) the
modulus of rupture in bending D
elongation or reduction of area from a tension test, (2) the depth of cup
modulus of rupture in torsion B
necking B
from a cupping test, (3) the radius or angle of bend from the bend test,
nominal stress see stress
or (4) the fatigue ductility from the fatigue ductility test (see Test
normal stress see stress
Method E796).
physical properties see mechanical properties
DISCUSSION—Malleability is the ability to deform plastically under
pin see mandrel (in bend testing)
repetitive compressive forces.
plastic true strain A
plunger see mandrel (in bend testing)

principal stress see stress elastic limit [FL ], n—the greatest stress which a material is

rate of creep E
DISCUSSION—Due to practical considerations in determining the
reduction of area B
elastic limit, measurements of strain, using a small force rather than
relaxation rate E
relaxed stress E zero force, are usually taken as the initial and final reference.
