Deformation of a Circular Elastic Tube between Two Parallel Bars: Quasi-Analytical Geometrical Ring Models

Figure 2

Overview geometrical nonbuckling ring models requiring two geometrical input parameters corresponding to a circular ring with perimeter and area : (a) elliptic cross-section with major axis and minor axis indicated and (b) stadium with rounded edges with minor axis and critical angle indicated from which the critical distance can be derived.
