... peak reaction forces and moments for each trial. Shear reaction forces were significantly greater (25.5 N–85.7 N) when the testing system was constrained compared to unconstrained (p < 0.029). The reaction moment was influenced by posture (p = 0.037), particularly in C5C6 spinal units. In 300...

... patient models and calculate the degree of shear-based blood damage (hemolysis). We used contrast-enhanced computed tomography angiography (CTA) data from three AAA patients who were treated with a novel endograft to build patient-specific models. For each of the three patients, we constructed a baseline...

...-dependent anisotropy was demonstrable in the intrusive and extrusive directions, such results may considerably simplify the development of constitutive laws for the PDL. As shown in Fig. 4 , a vertical force F was applied on the specimens. Thus, the ligament was subjected to a shear forces along...
