A New Finite Element Solver using Numerical Eigen Modes for Fast Simulation of Additive Manufacturing Processes
(University of Texas at Austin, 2013)
A new efficient numerical technique has been formulated for dimensional reduction and phenomenological
multi-scale simulation of additive manufacturing processes using finite element analysis. This technique is
demonstrated ...
An Integrated Approach to Cyber-Enabled Additive Manufacturing using Physics based, Coupled Multi-scale Process Modeling
(University of Texas at Austin, 2012)
The complexity of localized and dynamic boundary conditions in additive manufacturing
processes makes it difficult to track in-situ thermo-mechanical changes at different length scales
within a part using experimental ...
Layer by Layer Validation of Geometrical Accuracy in Additive Manufacturing Processes
(University of Texas at Austin, 2013)
Geometrical inaccuracy from shrinkage and residual stress-induced deformations are key sources of
defects in Additive Manufacturing (AM). In most AM processes the CAD model is represented by an STL
file which is sliced ...
A New Dynamic Mesh Method Applied to the Simulation of Selective Laser Melting
(University of Texas at Austin, 2013)
The process of Selective Laser Melting (SLM) involves the moving of a laser beam across a
powder bed to melt material layer by layer. From the standpoint of modeling, this simple
procedure is complicated to capture ...
Methods for Enhancing the Speed of Numerical Calculations for the Prediction of the Mechanical Behavior of Parts Made Using Additive Manufacturing
(University of Texas at Austin, 2013)
Finite element modeling (FEM) is one of the most common methods for predicting the thermo-mechanical
properties of 3D structures. Since FEM was developed primarily to analyze and optimize structures that would
then be ...
An Energy Dissipative Constitutive Model for Multi-Surface Interfaces at Weld Defect Sites in Ultrasonic Consolidation
(University of Texas at Austin, 2013)
A new finite element based constitutive model has been developed for quantification of energy
dissipation due to friction and plastic deformation at the mating interface of two surfaces during
the Ultrasonic Consolidation ...
