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