In order to detect defects in the surfaces of dry fabric and composite prepreg, this new vision-based tactile sensor roller prototype, TacRoller, is a three-colour reflective membrane roller-shape ...
Figure 1. Ultrasonic testing using pulse echo and through-transmission methods. Pulse echo (left and center) uses a transducer that sends and receives ultrasound energy, producing both A- and B-scan ...
In addition to conventional ultrasonic testing methods for high-rate aerospace production, Arcadia Aerospace Industries (AAI) specializes in custom solutions for a number of nondestructive testing ...
Researchers have improved flaw detection to increase confidence in metal parts that are 3D-printed using laser powder bed fusion. Researchers at the Department of Energy's Oak Ridge National ...
The small and complicated features of TSVs give rise to different defect types. Defects can form during any of the TSV ...
Nondestructive testing (NDT) refers to the inspection of materials to ensure their integrity and serviceability without damaging the components in the process. There are various NDT methods used by ...
In the last two decades, results obtained from structural reliability analysis (SRA) have increasingly led to formation of strategies for future safe operation of corroding oil and gas pipelines. 1-8 ...
Detecting macro-defects early in the wafer processing flow is vital for yield and process improvement, and it is driving innovations in both inspection techniques and wafer test map analysis. At the ...
