THREE-DIMENSIONAL PHOTOELASTICITY STUDY OF THICK-WALLED CYLINDRICAL SHELIS.

Abstract

A study was conducted to determine stress distributions in several types of thick-walled cylindrical shells. The stresses were determined by using both the embeddedpolariscope and stress-freezing methods for threedimensional photoelasticity. The study indicates that an approximate analytical solution for stresses in thick-walled cylinders with hemispherical heads is sufficiently accurate for structural design applications. Simple curved beam theory is also shown to give reasonable stress values for certain structures which take the form of a thick-walled half cylinder. Finally the study indicates that embedded polaroid elements perform satisfactorily under complex states of stress; therefore, the embedded-polariscope method represents a completely feasible approach for transient three-dimensional stress determinations.
