Figure 16
(a) Isochromatic contours in a homogeneous acrylic cylinder compressed by a C-clamp. Regions R₁ and R₃ have Saint-Venant stresses and strains due to imperfections in the clamp surfaces. Region R₂ has a homogeneous stress/strain distribution. (b) Idealized free-body diagrams of these regions, each with two regions of interest (green dashed squares). While one can infer the boundary stresses acting on the free-body diagrams of $[A_{R_2} \equiv B_{R_2}]$ from nominal stresses at the cylinder boundary, this is not possible for those in R₁ and R₃.
