Kriging-based optimization of functionally graded structures

چکیده

This work presents an efficient methodology for the optimum design of functionally graded structures using a Kriging-based approach. The method combines adaptive Kriging framework with hybrid particle swarm optimization (PSO) algorithm to improve computational efficiency process. In this approach, surrogate model is used replace high-fidelity structural responses obtained by NURBS-based isogeometric analysis. addition, impact key factors on modelling, as correlation function, infill criterion update model, and constraint handling assessed accuracy, efficiency, robustness. variables are related volume fraction distribution thickness. Displacement, fundamental frequency, buckling load, mass, ceramic objective functions or constraints. effectiveness accuracy proposed illustrated through set numerical examples. Results show significant reduction in effort over conventional

Topology Optimization Design of Functionally Graded Structures

1. Abstract Functionally Graded Materials (FGMs) possess continuously graded material properties and are characterized by spatially varying microstructures. Such materials are studied in conjunction with the concept of topology optimization design which determines holes and connectivities of the structure by adding and removing material in the extended fixed design domain. The objective is to d...

Design of Functionally Graded Structures Using Topology Optimization

The concept of functionally graded materials (FGMs) is closely related to the concept of topology optimization, which consists in a design method that seeks a continuum optimum material distribution in a design domain. Thus, in this work, topology optimization is applied to design FGM structures considering a minimum compliance criterion. The present approach applies the so-called “continuous t...

Sample-Based Synthesis of Functionally Graded Material Structures

Spatial variation of material structures is a principal mechanism for creating and controlling spatially varying material properties in nature and engineering. While the spatially varying homogenized properties can be represented by scalar and vector fields on the macroscopic scale, explicit microscopic structures of constituent phases are required to facilitate the visualization, analysis, and...
