Pneumatic shaping of materials with short-term creep

Abstract

Equations are derived for assessing the machining forces and damage in workpieces. The mechanical anisotropy of the initial material and the workpiece dimensions affect the stress–strain state, the flow kinematics, and the limits of pneumatic shaping with short-term creep, as here established. The mathematical models obtained and the corresponding theoretical results may be used in developing rotary-drawing technology.
