Surrogate model

Acoustic properties of foams, such as macroscopic transports and sound absorption, are significantly influenced by their local morphology. The present paper develops a polynomial chaos expansion (PCE)-based surrogate model for characterizing the microstructure-properties relationships of acoustic monodisperse foams.

In the first part of this paper, the Kriging metamodeling technique will be briefly reviewed. Then, we present a new learning function by accounting for the distance constraint in the selection process of the new training points (TPs) to enrich the Design of Experiment (DoE) of the built surrogate.

This study proposes a novel and efficient surrogate model for performing truss analysis based on graph theory and deep learning algorithms, which is applicable for various truss topologies with different load scenarios without requiring retraining as other Deep Learning (DL)-based counterparts.
