Comparison of Deformation and Strain Prediction and Measurement Techniques

Technique	Direct Output	Calculated Quantity
FEA	ui (x1, x3) u3(x1, x3 = 0)	Aij (x1, x3) = ∂ui / ∂xj → εij (x1, x3) → Δω(x1, x3)
EBSD	qk → Ãij (x1, x3 ≈ 0)	Closure relation →Aij (x1, x3 ≈ 0) → εij (x1, x3 ≈ 0)     →∫ A31 (x1, x3 ≈ 0)dx1 = u3 (x1, x3 ≈ 0)
AFM	u3(x1, x3 = 0)	∂u3 / ∂x1 = A31 (x1, x3 = 0)
CRM	Δω(x1, x3 ≈ 0)	Simple form of strain field → ε(x1, x3 ≈ 0)
