Thermal-node-link fast-FE model for deformation suppression in LWAM of thin-walled structures with machine learning assisted parameter optimization and prediction
Coaxial laser Wire Deposition Additive Manufacturing (LWAM) offers a cost-effective, high-deposition-rate solution for fabricating complex thin-walled aerospace and automotive components but suffers from deformation induced by thermal residual stresses. Conventional finite element models (FEM) for deformation predictio...
