Additively manufactured internal lattice structures offer a unique approach to lightweight components and adding multi-functionality. Design methods for parts based on lattices are emerging and include a family of topology optimization schemes for tailoring local cell density to service loadings. In order to gain confidence, these methods must be validated in a controlled manner. In this paper, we...
Thermally induced residual stresses and residual distortions in the additive manufactured (AM) parts are two of the major obstacles that are preventing AM technology from gaining wide adoption. In this work, a three-dimensional thermo-elastic-plastic model is proposed to predict the thermomechanical behavior in the laser engineered net shaping (LENS) process of Ti-6Al-4V using Finite Element Method...
