The deviatoric strain tensor in a cylindrically bent single-crystal plate of Si (R = 6.8 mm) can be estimated from the radius of curvature and the position within the thickness of the crystal. Even within a single crystal, the strain tensor elements can be quantitatively measured through the volume. Although the overall elastic behavior of the bent Si can be estimated from simple plate theory, close to edges the Si is actually a beam and exhibits more complex elastic bending behavior. |
