Finally, DENSE measurements were compared to reference-standard mechanical testing on aTAA specimens from surgical repairs. In total, 18 subjects were recruited, six healthy participants and 12 aTAA patients...

In a recent study, Chung et al. published an ML model capable of predicting rupture in abdominal aortic aneurysm that relied on computational finite element models informed by mechanical testing ( 26 ). It may be possible that further testing and validation of the ML model to predict yield...

Vaginal tissue from C57BL/6 female mice was mechanically tested using biaxial extension–inflation protocols before...

... of the polymeric film. A uniaxial mechanical testing device (Electroforce T3200, Bose Corp., Minneapolis, MN) was utilized as a general support structure, a means for high accuracy and high volume data acquisition, and a constant-rate electric displacement actuator. Figure 1 shows a comprehensive assembly...
