Rolls-Royce Uses Abaqus 2D Weld Simulation for Marine Fabrication
Rolls-Royce Marine applies Abaqus Welding Interface to model thermal and structural effects of multi-pass welding on pressure-vessel and ferritic steels.
The case study details how Rolls-Royce stress engineers use the Abaqus Welding Interface to create 2D finite element models of autogenous, groove, and ring welds. Temperature histories from thermal models feed structural analyses that predict distortion and residual stresses. Validation against neutron diffraction measurements confirms model accuracy for one-pass welds and supports further refinement of multi-pass simulations.
Abaqus Welding Interface automates weld bead, pass, and surface definition for 2D thermal-structural models.
Temperature-driven structural analysis predicts component distortion and peak residual stresses during welding.
Neutron diffraction measurements validate one-pass autogenous weld models with close correlation.
Automation of film and radiation surface loads reduces manual setup time for successive weld passes.
2D models serve as a stepping stone toward full 3D moving heat source weld simulations.
