Classification of the of the modelling studies on the UC AM process.
|Reference number||KPI||Process parameter (Variable)|
|||Linear weld density||Oscillation amplitude, welding speed, normal force, substrate temperature|
|||Solid state diffusion and bonding, microstructural deformation mechanisms||Surface effects (friction work, temperature)|
|||Linear weld density||Energy input to the workpiece within a single cycle of ultrasonic vibration, total energy input to the workpiece|
|||Yield stress||Thermal, acoustic softening|
|||Amplitude of contact friction stress and displacement||Vibration condition, substrate height|
|||Dislocations and bonding fragmentation|
|||Friction behaviour at the interfaces||Velocity of sonotrode, displacement amplitude of ultrasonic vibration, applied loads|
|||Residual stress and distortion||Support structure|
|||Weld strength||Contact pressure, amplitude, welding time|
|||Ultimate shear strength, ultimate transverse tensile strength||Tack force, weld force, oscillation amplitude, weld rate|
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
