Eigenvalue topology optimization
WebMentioning: 14 - SUMMARYIn this work, topology optimization is used to optimize the compliance or eigenvalues of prestressed plates. The prestress is accounted for by … WebMetallic blade-stiffened panels are optimized for various eigenvalue metrics of interest to the aerospace community. This is done via solid isotropic material with penalization-based topology optimization: the stiffeners are discretized into finite elements, and each element is assigned a design variable, which may vary from 0 (void) to 1 (solid). A known issue …
