Materials Properties
ABSTRACT
The mechanical parts can be manufactured from different types of materials. There are
basic materials, such as aluminum and copper and there are alloys. It is very important
to choose the correct material to manufacture the part since the mechanical properties
such as yield strength, elasticity module, and hardness determine the resistance to differ-
ent failure modes. Moreover, the material properties of the part can also have an effect on
the dimensions: if a part needs to be lighter but needs to carry some certain design force,
then a higher strength-to-weight ratio material should be used.
While it is easier to choose material for force/moment dependent failure modes, it is
harder to choose materials for time-dependent failure modes. It should be also noted that
the ease of manufacturing must be considered during the material selection process as
well as its availability
