Employee's performance and Kaizen events' success: does supervisor behaviour play a moderating role?
(Emerald, 2023-12-05)The study's goal was to identify the factors contributing to the practical completion of Kaizen events (KEs). The effect of the work-study man's characteristics, the supervisor's conduct and the autonomy of the Kaizen team ... -
Noninvasive measurement of local stress inside soft materials with programmed shear waves
(American Association for the Advancement of Science, 2023-03-08)Mechanical stresses across different length scales play a fundamental role in understanding biological systems¿ functions and engineering soft machines and devices. However, it is challenging to noninvasively probe local ... -
Analysis of in vivo skin anisotropy using elastic wave measurements and Bayesian modelling
(Springer, 2023-04-06)In vivo skin exhibits viscoelastic, hyper-elastic and non-linear characteristics. It is under a constant state of non-equibiaxial tension in its natural configuration and is reinforced with oriented collagen fibers, which ... -
Bending control and stability of functionally graded dielectric elastomers
(Elsevier, 2021-01-18)A rectangular plate of dielectric elastomer exhibiting gradients of material properties through its thickness will deform inhomogeneously when a potential difference is applied to compliant electrodes on its major surfaces, ... -
On the thermodynamic consistency of Quasi-linear viscoelastic models for soft solids
(Elsevier, 2020-12-15)Originating in the field of biomechanics, Fung's model of quasi-linear viscoelasticity (QLV) is one of the most popular constitutive theories employed to compute the time-dependent relationship between stress and deformation ... -
Wrinkling of soft magneto-active plates
(Elsevier, 2020-11-03)Coupled magneto-mechanical wrinkling has appeared in many scenarios of engineering and biology. Hence, soft magneto-active (SMA) plates buckle when subject to critical uniform magnetic field normal to their wide surface. ... -
An ultrasonic method to measure stress without calibration: The angled shear wave identity.
(Acoustical Society of America, 2020-12-03)Measuring stress levels in loaded structures is crucial to assess and monitor structure health and to predict the length of remaining structural life. Many ultrasonic methods are able to accurately predict in-plane stresses ... -
