XIGA: An eXtended IsoGeometric Analysis approach for multi-material problems
L. Noel, M. Schmidt, K. Doble +2
Multi-material problems often exhibit complex geometries along with physical responses presenting large spatial gradients or discontinuities. In these cases, providing high-quality…
Automated processing of X-ray computed tomography images via panoptic segmentation for modeling woven composite textiles
Aaron Allred, Lauren J. Abbott, Alireza Doostan +1
A new, machine learning-based approach for automatically generating 3D digital geometries of woven composite textiles is proposed to overcome the limitations of existing analytical…
Topology Optimization under Microscale Uncertainty using Stochastic Gradients
Subhayan De, Kurt Maute, Alireza Doostan
This paper considers the design of structures made of engineered materials, accounting for uncertainty in material properties. We present a topology optimization approach that opti…
Minimum Feature Size Control in Level Set Topology Optimization via Density Fields
Jorge L. Barrera, Markus J. Geiss, Kurt Maute
A level set topology optimization approach that uses an auxiliary density field to nucleate holes during the optimization process and achieves minimum feature size control in optim…
Reliability-based Topology Optimization using Stochastic Gradients
Subhayan De, Kurt Maute, Alireza Doostan
This paper addresses the computational challenges in reliability-based topology optimization (RBTO) of structures associated with the estimation of statistics of the objective and…
Ambiguous phase assignment of discretized 3D geometries in topology optimization
Jorge L. Barrera, Kurt Maute
Level set-based immersed boundary techniques operate on nonconforming meshes while providing a crisp definition of interface and external boundaries. In such techniques, an isocont…
