Elastic-Plastic Analysis of Open-End, Transversely-Isotropic Tubes Under Internal Pressure. Part III: Strain Solution by Deformation Theory

摘要

The report contains an elastic-plastic analysis of a circular, open-end, unrestricted tube subjected to internal pressure of sufficient magnitude to cause plastic deformation. The axial stress is assumed to vanish identically throughout the tube. The material is homogeneous but transversely isotropic about the radius vector in both elastic and plastic regions. In the plastic portion, Hill's orthotropic yield criterion and the associated deformation theory is used. Expressions for strain components are obtained and the results are shown graphically. (Author)
