| Abstract Scope |
While conventional joining techniques—such as bolting, welding, and adhesives—are widely used, they often suffer from poor environmental durability and limited geometric adaptability when pairing dissimilar materials. Modern engineering demands high-performance, rapidly produced interfaces capable of maintaining integrity under extreme conditions. A significant gap exists, however, in the ability to precisely calibrate interfacial strength and failure behavior through localized geometric design. This research bridges that gap by applying topology optimization to create mechanically interlocking joints specifically for multi-material additive manufacturing. By integrating interfacial weakness directly into the optimization framework, this method produces robust, assembly-free connections that overcome the inherent limitations of traditional material bonding. |
