Ideal case (A) schematic representation of hallow curved shaft used in ideal case example with radius of curvature R, inner diameter D1 and outer diameter D2. (B) Percentage difference of critical strain in curved beam and straight beam model from that of finite element for various R/D2 (C–E) contour plot of maximum principal strain for hollow curved beam R/D2 = 3 based on straight beam (left figure), curved beam (middle figure) and finite element analysis (right figure).
