Abstract
In the area of elastic deformation there is linear dependence
between the applied stress and final deformation, which is
described by the Hooke´s law. Thus stress and strain are
proportional to each other and constant of proportionality is
termed as modulus of elasticity (even. Young´s modulus). So
this material constant characterizes the elastic deformation
behavior of the given material and its magnitude represents the
very important material constant in all industrial branches and
mainly determines the dimensions for the given parts. That is
why it´s truly very important to precisely measure its values for
different materials. Because of this were in this article used two
methods for measurement Young´s modulus E (MPa) – static
tensile test and three-point bend test. Main aim was to obtain
statistical evaluation about influence of these testing methods
on the final values of modulus of elasticity.
