Transient Temperature History for Single-Layer Wire-Arc Directed Energy Deposition
Description
This dataset contains a single transient temperature history from a 3D heat-transfer finite element simulation of a single-layer wire-arc directed energy deposition (WA-DED) process using a Goldak double-ellipsoidal moving heat source. The computational domain is 40 mm × 6 mm × 4 mm and the simulated duration is 4 s. Model Setting: FE Software: Abaqus 2023 ّFE Element type: DC3D8 Solver Settings: Implicit time-integration approach via Newton–Raphson iteration Mesh size = 1e-4 m Temporal increment = 5e-3 s Travel speed = 1e-3 m/s Goldak heat source parameters (according to https://doi.org/10.1007/s00466-019-01748-6): a_f = 2.57e−3 m a_r = 6.00e−3 m b = 3.00e−3 m c = 6.00e−3 m f_f = 0.6 f_r = 1.4 Material and boundary properties: Density ρ = 7850 kg/m^3 Specific heat Cp = 620 J/(kg·K) Thermal conductivity k = 45 W/(m·K) Convection coefficient h = 20 W/(m^2·K) Emissivity ε = 0.2 [–] Stefan–Boltzmann constant σ = 5.670374419e−8 W/(m^2·K^4)
