Article Synopsis
- * The study introduces a new technique called the image-based ultrasonic cell shaking test, allowing for controllable deformation of cells and real-time quantification of their responses to ultrasonic vibrations.
- * This method combines ultrasonic vibrations with high-speed microscopic imaging to analyze cell deformation and subsequent biological responses, potentially enhancing knowledge of ultrasonic surgical cutting and mechanobiological pathways.
The standard edge crush test (ECT) allows the determination of the crushing strength of the corrugated cardboard. Unfortunately, this test cannot be used to estimate the compressive stiffness, which is an equally important parameter. This is because any attempt to determine this parameter using current lab equipment quickly ends in a fiasco.

As a representative example an unsymmetrical 5-ply sample (with E and B flute) was used in this study. In order to exclude unreliable displacement measurement in the standard edge crush test, virtual strain gauges were used.

- - The virtual fields method helps identify material parameters through analyzing full-field deformation data, focusing on new automatically-defined virtual fields for non-linear models.
- - These sensitivity-based virtual fields improve parameter identification by minimizing noise interference, and while tested on small strain plasticity, they apply to various non-linear models.
- - When comparing these new virtual fields to traditional stiffness-based and manual methods, the sensitivity-based approach consistently yielded better results, particularly in noisy data conditions.
