Abstract
En 中文
• Exact geometry via isogeometric analysis removes CAD–analysis mismatch • Mapping-based interpolation yields precise 0–1 multi-material layouts • Fewer iterations cut total cost despite heavier per step computation • Sharper boundaries and lower compliance than conventional methods • Tunable support radius balances detail, continuity, and performance • More control points refine geometry and improve optimization quality
Keywords:
isogeometric analysis
multi-material optimization
precise interpolation
compliance minimization
tunable support radius
