4.3 The influence of Coefficient of friction:
From the Fig 4.20.In case of steel Radial Strain is observed to increase from 0.378 to 0.389 as the
coefficient of friction is varying from 0.1 to 0.45.From the Fig 4.21.In case of copper as the coefficient of
friction is varied from 0.1 to 0.45, the radial strain is decreasing gradually from 0.404 to 0.401.From the Fig
4.22.As the coefficient of friction is varied from 0.1 to 0.45 in case of steel the thickness strain is increasing
from 0.2146 to 0.239. From the Fig 4.23.As the coefficient of friction is varied from 0.1 to 0.45 in case of
copper the thickness strain is increasing from 0.1954 to 0.1993. From the Fig 4.24.In case of steel as the
coefficient of friction is varied from 0.1 to 0.45 hoop strain is decreasing from 0.01713 to 0.1273 and where as
in copper it is decreasing from 0.0233 to 0.0179.
From the Fig 4.25.As the coefficient of friction is varied from 0.1 to 0.45 von mises stress is increasing
from 4.545E2 to 4.666E2 in case of steel.
From the Fig 4.26In case of copper also as the coefficient of friction is varied from 0.1 to 0.45 vonmises
stress is increasing from 3.423E2 to 3.452E2.From the Fig 4.27.As the coefficient of friction is varied
from 0.1 to 0.45 radial stress is increasing from 28.29 to 30.66 Mpa in case of steel.From the Fig 4.28.In case of
copper as the coefficient of friction is varied from 0.1 to 0.45 radial stress is decreasing from 22.47 to 22.25
Mpa. It is interesting to note that radial stress is increasing in steel and in copper radial stress is decreasing as
the coefficient of friction is varied from 0.1 to 0.45.From the Fig 4.29.The thickness stress is increasing from
15.26 to 34.99Mpa in case of steel as the friction is increased whereas in copper thickness stress remains
constant from friction value of 0.1 to 0.2 and after 0.2 thickness stress is increasing.From the Fig 4.30.Hoop
stress is increasing from 4.39E2 to 4.522E2 Mpa as the coefficient of friction is varied from 0.1 to 0.45 in case
of steel.From the Fig 4.31.whereas in case of copper Hoop stress is increasing from 4.39E2 to 4.522E2 Mpa as
the coefficient of friction is varied from 0.1 to 0.45.
