Shrink-wrapping of cylindrical parts
Press, shrink, and cryogenic fittings

The shrinking of a ring onto an axle can be treated, provided that the deformation is free according to the axial directionz, using the two-dimensional elasticity formulas in polar coordinates (r, θ) using the following concepts:

• constraints σ_r, σ_θ and τ_rθ are defined as shown in figure 3. These are the components of the constraints applied to the facets, respectively called radial, normal to the radius vector (axis 1 in figure) 3a) and orthoradial normal tangent to the circle with center O passing through the point under consideration (axis 2 in figure)...
