Welding simulations have the potential to address shipbuilding challenges such as thin-plate distortion. Welding simulation accuracy is dependent on high-temperature material property databases. The Naval Surface Warfare Center, Carderock Division, in collaboration with the Welding Engineering Program at The Ohio State University, generated and published pedigreed, temperature-dependent material property databases for six Navy-relevant steels. Published properties include specific heat, thermal conductivity, coefficient of thermal expansion, elastic modulus, yield strength, ultimate tensile strength, and flow stress, collected from room temperature to near melting. Material properties were compared to evaluate trends and anomalies across the alloys, and a representative weld was simulated in SYSWELD to compare the effects of each material. Variance was found in the mechanical and thermal simulation results across the alloys modelled. The work presented suggests that in comparisons across similar alloys within a material family, detailed and reliable high-temperature material property databases remain essential to accurate ICME modelling. |
