Hyper‐reduced order models for accelerating parametric analyses on reinforced concrete structures subjected to earthquakes

This paper combines a hyper‐reduction procedure, the proper orthogonal decomposition unassembled discrete empirical interpolation method, with a non‐iterative α‐operator splitting (α‐OS) time‐integration scheme for accelerating parametric analyses…

Identification of the effective interface between the homogenized phases of a dual-weave 3D composite

Hybridization enhances composite properties by assembling several reinforcement materials. In woven composites, the distribution of different yarns can induce a macroscopic heterogeneity in the thermomechanical properties, which can be considered in…

Empowering PGD-based parametric analysis with Optimal Transport

The Proper Generalized Decomposition (PGD) is a Model Order Reduction framework that has been proposed to be able to do parametric analysis of physical problems. These parameters may include material properties, boundary conditions, etc. With this…

Effects of Filtering and Current-angle Adjustment on the Multi-Material Topology Optimization of a 3-phase Stator

This paper investigates MMTO methods to design 3-phase PMSM stators, showing that a usual gradient descent leads to non-manufacturable local optima. A multi-material density filtering consistent with the antiperiodic boundary conditions smooths the…
