Multi-physics topology optimization of functionally graded controllable porous structures: Application to heat dissipating problems

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...

An isogeometric approach to topology optimization of multi- material and functionally graded structures

Alireza H. Taheri, Krishnan Suresh* Department of Mechanical Engineering, UW-Madison, Madison, Wisconsin 53706, USA. * Corresponding author, email: [email protected] Abstract A new isogeometric density based approach for the topology optimization of multi-material structures is presented. In this method, the density fields of multiple material phases are represented using the isogeometric NURBS-...

Design of Functionally Graded Phononic Band Gaps Using Topology Optimization

Phononic band-gap materials prevent elastic waves from propagating at certain frequency ranges. These materials are called Phononic Crystals (PCs). PCs have been applied to manufacture frequency filters, vibration protection devices, waveguide and to improve ultrasound imaging transducers. Periodic band-gap materials are designed by choosing the location and the size of the band gaps. Many work...
