articleOpen accessSenior authorCorrespondingFinite element-based characterization of interface strength in Ultrasonic Additive Manufacturing (UAM) is crucial for accurately simulating failure behavior in UAM components and reducing experimental requirements. This study introduces a testing methodology using specially designed dovetail-shaped UAM samples to characterize UAM interfaces for finite element modeling. These samples enable loading in three distinct configurations, generating varied stress distributions at the weld interface to induce failure. A fracture mechanics approach, utilizing the cohesive zone model (CZM), is applied in finite element method (FEM) simulations to characterize the interface behavior. Tests in the three configurations are simulated in FEM and the CZM parameters are calibrated against the experimental data to accurately characterize the weld interface. These calibrated parameters are suitable for broader failure simulations of UAM structures. Model validation was achieved by accurately predicting experimental fracture behavior for a different loading configuration, with an error of only 10.1%. • Finite element methodology for UAM interface fracture characterization • Dovetail UAM samples tested under distinct loading configurations • Cohesive zone model formulated and calibrated from experimental data • FEM–CZM model validated for arbitrary interface loading conditions

articleSenior authorCorrespondingProcess modeling of ultrasonic additive manufacturing (UAM) is critical for optimizing process settings with minimal experimental trials. In this research, a parameter termed weld quality ( Q w ) is formulated based on hardness and process settings to predict the shear strength of aluminum alloy 6061 (AA6061) UAM weld interfaces between similar and dissimilar tempers. Four AA6061 tempers are investigated: O (annealed), H18 (cold rolled with 75% thickness reduction), T4 (solution heat treated and naturally aged), and T6 (solution heat treated and artificially aged). Shear samples quantify the shear strength at foil-to-foil and baseplate-to-foil interfaces, with near-gapless bonding observed. The Q w parameter linearly correlates with shear strength measurements, achieving a coefficient of determination ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline" overflow="scroll"> <mml:msup> <mml:mi>R</mml:mi> <mml:mn>2</mml:mn> </mml:msup> </mml:math> ) of 91.18%.
Smart lightweighting of vehicle structures (Conference Presentation)
2025-05-12
article1st authorCorrespondingThis presentation focuses on the lightweighting of vehicle structures by means of two mechanisms. One mechanism is the functionalization of structures through the incorporation of sensors, actuators, and energy harvesting systems based on piezoelectrics and other active materials. The other revolves around advanced manufacturing to enable the integration of carbon fiber into metallic vehicle structures. We have made significant progress toward the functionalization and multi-material integration of vehicle structures through the use of ultrasonic additive manufacturing (UAM), a solid-state metal 3D printing process that allows for seamless joining, embedding, and integration of structural metals, organic polymers, shape memory materials, ceramics, electronics, and high-value components. UAM uses high-power piezoelectric transducers to weld metal foils additively, encapsulate high-value materials into metal structures, and join dissimilar materials. The research activities discussed here are conducted within the Smart Vehicle Concepts Center, a graduated NSF IUCRC that was established to accelerate the transition of advanced materials from the laboratory to the mobility industry.
