Applied Optimization, Inc. (AO) is developing an Integrated Computational Materials Engineering (ICME) solidification science-based additive manufacturing (AM) framework for multi-scale thermal and microstructure modeling, melt pool thermal-fluid flow analysis, thermodynamic and kinetic models, and a cellular automata (CA) framework. The dynamics of solidification interface velocity will be modeled using interface response function theory to predict the material inhomogeneities caused by the phase selection phenomena and the AM scan strategy. The evolution of the solidification front will be traced within the CA grid to predict the solidification grain growth and orientation and the sub-grain morphology and texture. AO seeks to identify DoD Prime contractor and Programs focused on AM to include powder bed AM process optimization for the mitigation of build defects and microstructure inhomogeneities.
Since 1995, Applied Optimization, Inc. (AO) has collaboratively developed innovative solutions in material science to address technical challenges for industry, NASA, and the DoD. AO is developing a hardware-software system for layer-by-layer nondestructive inspection and near-real-time determination of spatial distribution material defects in metallic parts, fabricated via selective laser melting (SLM) processes. AO’s hardware is comprised of off-the-shelf laser scanners (profilometer) and precision linear motion, implemented into the deposition chamber of commercial SLM equipment. AO’s software implements signal processing algorithms for data reduction and processing of collected 3-D top-surface build geometry/roughness data to predict material defects. AO’s capability employs physics-based models to correlate the phenomenology of interaction between surface roughness and material defects and to provide voxel-by-voxel anomaly flagging. AO seeks to identify DoD Prime contractor and Programs focused on AM to include selective laser melting (SLM) process optimization.
Applied Optimization, Inc. (AO) is developing Integrated Computational Materials Engineering (ICME) models and software to support additive manufacturing (AM) development of conformal heat exchangers (HeX) for power electronics hardware. The conformal geometry of cooling channels is optimized to attain higher thermal efficiency. ICME optimization ensures the manufacturability of quality metallic parts from a variety of AM machines at different geographic locations. AO's team of scientists, engineers, and software developers’ modeling and simulation capabilities has advanced the understanding of the state-of-the-art in additive manufacturing (AM) processing. Employment of AM leads to innovative HeX designs capable of more efficiently removing heat because these designs eliminate or severely reduce joints. AO seeks to identify DoD Prime contractor and Programs focused on AM and thermal management optimization.
