Stress and frequency optimization of prismatic sandwich beams with structural joints: Improvements through accelerated topology optimization
Published 2025“…The inexact recycled implicitly restarted Lanczos method is proposed, providing a novel approach to efficiently solving eigenvalue problems by recycling eigenvectors and relaxing convergence tolerances, significantly speeding up the process. The topology optimized beams are compared to conventional prismatic sandwich beams (X-core, Y-core, corrugated-core, and web-core), which are optimized using a global evolutionary algorithm. …”
