Mechanical
Properties
Of
Materials
- Stress
- Stress = Force
Divided by
Cross Sectional
Area (Internal
reactive forces
transmitted
through the
material
subjected to
loading)
- 2 Types of
Stress =
Normal
Stress and
Shear Stress
- Unit for Stress = Pascal
- Strain =
Dimensionless is
the amount of
elongation per
unit length
- Unit for Stress = Pascal
- 2 Types of
Stress =
Normal
Stress and
Shear Stress
- Stress = Force
Divided by
Cross Sectional
Area (Internal
reactive forces
transmitted
through the
material
subjected to
loading)
- Youngs Modulus
of Elasticity
- Youngs Modulus
is the measure
of how Rigid or
Stiff a material is
- Tensile
Testing
=
Tensile
tests
can tell
us a
number
of
material
properties
- Tensile tests can tell
us that Strain and
Stress are
proportional to one
another
- Can also tell us
the Elastic or yield
point, As in if the
load is removed
before it reaches a
certain stress level
the material will
go back to its
original form. Also
known as " Elastic
Behaviour"
- UTS = Point at which the load bearing
ability of the specimen peaks. If more is
added to material this will result in load
bearing capacity of the material being
diminished
- Ductile Materials
will begin to
neck an then
Break
- Breaking or Fracture Strength
- Breaking or Fracture Strength
- Brittle Materials will fracture
- Ductile Materials
will begin to
neck an then
Break

of which the
