STRESS STRAIN CURVE FOR VARIOUS ENGINEERING MATERIALS.


Stress strain curve for various engineering materials.
Aim:

          To study the behaviour of different engineering materials.

Theory:

           The mechanical properties of materials used in engineering are determined by tests performed on small specimen of materials.

The various topics to be discussed are:
a)      Tension test
b)      Extensometer
c)      Nominal stress
d)     Nominal strain
e)      Stress strain diagram
f)       Proportional limit
g)      Yielding
h)      Yield stress
i)        Lateral contraction
j)        Elasticity
k)      Partially elastic
l)        Plasticity
m)    Plastic flow
n)      Creep
o)      Hooke’s law
p)      Poisson’s ratio
q)      Offset yield stress
r)       Young’s modulus
s)       Poisson’s ratio
t)       Modulus of resilience

Result:
      Thus, the various behaviour of engineering materials are studied.
