Plastic Strains in Thick Hollow Cylinders Overstrained by Internal Pressure

摘要

Equations are derived relating wall ratio to plastic strains resulting from overstraining thick hollow cylinders. That the equations are applicable, is evidenced by comparison with statistical data from the inspection records of guns coldworked at Watertown Arsenal in the current production activities and by agreement with experimental test data. Equations are developed for (1) Strain Ratio, (2) Flow Factor, (3) Longitudinal Strains, (4)Longitudinal Shrinkage in Tapered Sections, and (5) Strain Distribution Through the Cylinder Wall.
