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…
Topology optimization of high-performance optomechanical resonator
Yincheng Shi, Fengwen Wang, Dennis Høj +2
High quality mechanical resonators are critical for driving advances in quantum information technologies, precision sensing, and optomechanics. However, achieving compact resonator…
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…
Buckling and yield strength estimation of architected materials under arbitrary loads
Morten N. Andersen, Yiqiang Wang, Fengwen Wang +1
Buckling strength estimation of architected materials has mainly been restricted to load cases oriented along symmetry axes. However, realistic load scenarios normally exhibit more…
Ultra-coherent nanomechanical resonators based on inverse design
Dennis Høj, Fengwen Wang, Wenjun Gao +3
Engineered micro- and nanomechanical resonators with ultra-low dissipation constitute the ideal systems for applications ranging from high-precision sensing such as magnetic resona…
3D architected isotropic materials with tunable stiffness and buckling strength
Fengwen Wang, Ole Sigmund
This paper presents a class of 3D single-scale isotropic materials with tunable stiffness and buckling strength obtained via topology optimization and subsequent shape optimization…
