Chapter 8 – Combined Loading CL = 2 or more stresses at a given point.
8.1 Thin-Walled (r/t > 10) Pressure Vessels: Circumferential or Hoop Stress: s1 uniform throughout wall! Assumption: Thin walled so assume stress uniform throughout the wall! Normal stress in the hoop direction
Longitudinal Stress: Assumption: Thin walled so assume stress uniform throughout the wall! Normal stress in the longitudinal direction Note, this stress = hoop stress/2
Summary: Cylindrical Pressure Vessels: Circumferential or Hoop Stress Longitudinal Stress
Elastomer volume = 13.8 in3 (was 16.2 in3) Wall thickness = .10” RJM 6/2/04
