Concurrent Topology and Fiber Path Optimization for Continuous Fiber Composite Under Thermo-Mechanical Loadings

This presentation introduces a concurrent topology and fiber-path optimization for continuous fiber composite under thermos-mechanical loadings. The goal is to minimize the structural compliance of with coupling while satisfying volume fraction constraint, ensuring manufacturability by using fibers avoiding appearance over thin members. Level-set function utilized represent both shape boundary path. zero isocontour level-set updated sensitivity analysis anisotropic composite, paths in are given functions determined from boundary. A level-set-based mesh evolution method introduced following classical based on ersatz-material approach during process further improve result’s accuracy. thickness control step variational also incorporated enlarge members when they appear ensure optimized design manufacturable. influences thermal loadings evaluated applying different temperature increases composites, showing their large impacts shapes. developed algorithm has been applied several numerical examples demonstrate its effectiveness, that very effective reducing composite.
