摘要：
A method of radially expanding and plastically deforming tubular members (10, 100, 200) is provided that includes selecting a tubular member, determining an anisotropy value and a strain hardening value for the selected tubular member (10, 100, 200), multiplying the anisotropy value times the strain hardening value to generate an expandability value for the selected tubular member (10, 100, 200); and if the expandability value is greater than 0.12, then radially expanding and plastically deforming the selected tubular member (10, 100, 200).
