Yield and Buckling Stress Limits in Topology Optimization of Multiscale Structures
Christoffer Fyllgraf Christensen, Fengwen Wang, Ole Sigmund
This study presents an extension of multiscale topology optimization by integrating both yield stress and local/global buckling considerations into the design process. Building upo…
Extremal Structures with Embedded Pre-Failure Indicators
Christoffer Fyllgraf Christensen, Jonas Engqvist, Fengwen Wang +2
Preemptive identification of potential failure under loading of engineering structures is a critical challenge. Our study presents an innovative approach to built-in pre-failure in…
Topology Optimization of Multiscale Structures Considering Local and Global Buckling Response
Christoffer Fyllgraf Christensen, Fengwen Wang, Ole Sigmund
Much work has been done in topology optimization of multiscale structures for maximum stiffness or minimum compliance design. Such approaches date back to the original homogenizati…
Architecting materials for extremal stiffness, yield and buckling strength
Fengwen Wang, Ole Sigmund
This paper proposes a methodology for architecting microstructures with extremal stiffness, yield, and buckling strength using topology optimization. The optimized microstructures…
