From: Finite element method-enhanced neural network for forward and inverse problems
Input variable | Distribution | Mean | Standard deviation |
|---|---|---|---|
Horizontal cross-section area \(A_h (m^2)\) | Normal | \(1.0 \times 10 ^{-3} \) | \(1.0 \times 10 ^{-4} \) |
Vertical cross-section area \(A_v (m^2)\) | Normal | \(2.0 \times 10 ^{-3} \) | \(2.0 \times 10 ^{-4} \) |
Horizontal Young’s modulus \(E_h (Pa)\) | Normal | \(2.1 \times 10 ^{11} \) | \(2.1 \times 10 ^{10} \) |
Vertical Young’s modulus \(E_v (Pa)\) | Normal | \(2.1 \times 10 ^{11} \) | \(2.1 \times 10 ^{10} \) |
Vertical forces \(P1-P6 (N)\) | Normal | \(-5.0 \times 10 ^{5} \) | \(5.0 \times 10 ^{4} \) |
