All data measurements were conducted bilaterally by the same expert ultrasound diagnostician for consistency. The probe was switched to the SWE mode, and the sampling frame was set as 10 mm x 10 mm in the area of interest with a depth of 1.2 cm. After the image was stabilized, the . Shear wave elastography (SWE) is an emerging and promising ultrasound modality, and is more recently employed in the diagnosis of musculoskeletal (MSK) .
Recently introduced on clinical scanners, shear-wave elastography (SWE) is considered to be more objective, quantitative, and reproducible than compression .logists with 14 and 15 years of experiences in abdominal ultrasound performed all examinations independently. Furthermore, 8 chronic obstructive pulmonary disease (COPD) patients were examined by only the first radiologist. Gray . A symmetric version of the double-notch shear test is proposed for direct measurement of the interlaminar shear strength under moderate through-thickness compression.All data measurements were conducted bilaterally by the same expert ultrasound diagnostician for consistency. The probe was switched to the SWE mode, and the sampling frame was set as 10 mm x 10 mm in the area of interest with a depth of 1.2 cm. After the image was stabilized, the Q-box was started for shear wave elasticity measurement.
Background Characterizations of mechanical properties for composite structures are challenging due to their heterogeneity and anisotropy which lead to more measurements of elastic constants and sophisticated testing apparatus compared to isotropic materials. Measuring in-plane shear modulus for composites with small cross-section or large aspect ratio often . Pulse-echo mode thickness measurements are one of the most commonly employed ultrasound non-destructive evaluation (NDE) techniques. The procedure consists in exciting 0 ∘ waves using an ultrasound transducer (UT). These waves propagate into the material that is to be inspected at an angle that is normal to the surface and reflect from the back-wall . • A new method for simultaneous crack detection and thickness measurement using a single probe is discussed [112]. It was found that "crack-like defects with depth 0.3 mm (0.2λ) or higher can .
Curing-induced internal stress can also concentrate around pigments and fillers. The particulates represent discontinuities in the matrix, and the states of stresses are different around these, resulting in more localized defects. 9 Generally, coatings exhibit a critical cracking thickness, which depends on the formulation and exposure conditions and can range from . Here a modified symmetric DNS test has been developed and performed for direct measurement of the interlaminar shear strength of laminated composite materials under moderate through-thickness compression. . An assessment of through-thickness shear tests for initiation of fatigue failure. Compos Part A, 41 (11) (2010), pp. 1570-1578.

Assessment of the abdominal muscles at rest and during abdominal drawing-in manoeuvre in adolescent physically active girls: A case–control study. J .The shear test therefore permits the measurement of both shear modulus and shear hysteresis properties when the fabric is sheared in both directions. The physical parameters computed in the shear test are: G - shear modulus, which is the slope of the shear curve(N/m), 2HG - hysteresis width at a shear angle of 0.5 degrees (N/m), and
The intra-rater reliability values for thickness measurements of the masseter, temporalis, and lateral pterygoid muscles were 0.976 (95% confidence interval [CI], 0.939–0.991), 0.897 (95% CI, 0.682–0.969), and 0.966 (95% CI, 0.893–0.990), respectively. . Quantitative shear wave speed assessment for muscles with the diagnosis of taut . A novel method for the characterization of through-thickness shear constitutive behavior of composites. Author links open overlay panel Ziqing Hao a, Hongjun Ke b, Na Li b, Xiaoyu Wang a, Jinming Li a, Liu Liu a. . USA) was used for full-field deformation measurement and assessment of engineering strain components on specimen surfaces .
The velocity of shear wave transmission relies on the density and elasticity of the tissue in the vicinity [15]. According to the equation relating the local shear wave velocity to stiffness, shear wave elastography is used to estimate stiffness: Stiffness = density × (shear wave velocity)2 [25]. In our study, the carotid stiffness values . The Importance of Preconditioning for the Sonographic Assessment of Plantar Fascia Thickness and Shear Wave Velocity Sensors (Basel). 2024 Jul 14;24(14):4552. doi: 10.3390/s24144552. Authors Conor Costello . Sonographic measurements of thickness and shear wave (SW) elastography are useful tools for detecting such changes and guide clinical . All data measurements were conducted bilaterally by the same expert ultrasound diagnostician for consistency. The probe was switched to the SWE mode, and the sampling frame was set as 10 mm x 10 mm in the area of interest with a depth of 1.2 cm. After the image was stabilized, the Q-box was started for shear wave elasticity measurement.the effective shear stress τAB based on the measurement of the machining forces during orthogonal cutting experiments. However, Equation (5a) is not exploited since it includes

Background: Ultrasound is a useful tool to evaluate and quantify skin lesions. Few studies have assessed the criterion validity of skin ultrasound in systemic sclerosis (SSc). The aims of the study were to investigate skin thickness and stiffness using ultrasound and shear wave elastography (SWE) in SSc and to validate skin ultrasound measurements against .

For each gridline, the distance from the coating-substrate interface to the last contact with the porous coating material is measured as the coating thickness. The average of all of the coating thickness measurements obtained from all the measured fields is the mean coating thickness for that coating. Volume Percent Void (ASTM F1854 Section 9.2)
However no tests for pure interlaminar shear strength measurement were performed. Hine et al.
