(a), (c), (e) Diagrams of MMA units with different patterns: (a) round: L = 10 mm, t = 1.5 mm, and variable r from 0 to 4 mm; (c) cross: L = 12 mm, a = 0.6 mm, t = 5.4 mm, and variable b (1.8 mm, 3.0 mm, 4.2 mm, and 5.4 mm); (e) concentric annulus: L = 10 mm, r1 = 3 mm, t = 1.5 mm, and variable r2 from 1.4 mm to 2.6 mm. (b), (d), (f) The symmetry models for the three patterns, respectively.
