On the Importance of Geometric Nonlinearity and Temperature-Dependent Properties in Multi-Material Thermo-Mechanical Topology Optimization
Shirin Hosseinmardi, Xiangyu Sun, Ramin Bostanabad
Thermo-mechanical compliant devices are commonly designed with small-strain linear elasticity and temperature-independent material properties, even though they might operate hundre…
Multi-material Multi-physics Topology Optimization with Physics-informed Gaussian Process Priors
Xiangyu Sun, Shirin Hosseinmardi, Amin Yousefpour +1
Machine learning (ML) has been increasingly used for topology optimization (TO). However, most existing ML-based approaches focus on simplified benchmark problems due to their high…
Compliance Minimization via Physics-Informed Gaussian Processes
Xiangyu Sun, Amin Yousefpour, Shirin Hosseinmardi +1
Machine learning (ML) techniques have recently gained significant attention for solving compliance minimization (CM) problems. However, these methods typically provide poor feature…
Should We Simultaneously Calibrate Multiple Computer Models?
Jonathan Tammer Eweis-Labolle, Tyler Johnson, Xiangyu Sun +1
In an increasing number of applications designers have access to multiple computer models which typically have different levels of fidelity and cost. Traditionally, designers calib…
Localized Physics-informed Gaussian Processes with Curriculum Training for Topology Optimization
Amin Yousefpour, Shirin Hosseinmardi, Xiangyu Sun +1
We introduce a simultaneous and meshfree topology optimization (TO) framework based on physics-informed Gaussian processes (GPs). Our framework endows all design and state variable…
