Critical State of a Thin-Walled Cylindrical Shell Containing an Interlayer Fabricated from a Material of Lesser Strength

COMPRESSORS, PUMPS, AND PIPELINE FITTINGS
First Online:

The stress state and strength of thin-walled cylindrical shells containing straight and spiral interlayers of a material of lesser strength are investigated. Dependences of the critical internal pressure in thin-walled shells on the slope of the layer of lesser strength, the coefficient of biaxiality of the loading, the relative thickness of the layer of lesser strength, and the coefficient of mechanical nonuniformity are obtained. A comparative theoretical analysis of the strength of seamless, straight-seam, and spiral-seam large-diameter pipes containing interlayers of lesser strength in the seams is carried out.
