The
mechanical properties of materials are
fundamental
to their utility in engineering
applications.
For most uses the material is required to stay in its elastic range and
well below the stress at which fracture will occur. During the fabrication
of components, the material is frequently taken into the plastic range
as its geometry is changed to suite the design. It is inadequate to only
consider mechanical properties at room temperature and
under
steady load conditions. In this section an
introduction
to general mechanical behavior will be given, followed by a discussion
of elastic properties. Following sections will cover plastic deformation
and failure modes. |
