Abstract:
The hoop stress and stress concentration factor distributions
in a closed ended thick-walled cylinder with a chamfered
cross bore under intemt,al pressure were inaestigated.
The finite element method of stress analysis wts used for
this study. The effect of changing chamfer angle, for a
fired chamfer size, on the hoop stress and stress concentration
factor distributions wt,s inaestigated. The effect of
changing the chamfer length, fo, a fired chamfer angle, on
the hoop stress distributions and stress concentration foctors
was also inuestigated. The optimum chamfer angle
and chamfer length fo, any cylinder configuration was established.
The study reuealed that adding chamfers to cross
bores causes a, redistribution and reduction of the stresses
attained in intemrally pressurized thick-walled cylinders.
For o, thick cylinder of a giuen thickness ratio and cross
bore diameter, it was obseraed that the stresses were a minimum
at a specifi,c chamfer angle and size.
