Pipette aspiration is a widely used biomechanical technique for measuring the mechanical properties of cells and soft tissues. In this study, we present a computational model of pipette aspiration based on the finite elementmethod, as implemented in FreeFEM++. This model simulates tissue deformation under suction pressure, enabling us to analyze the system’s frequency response. Our results...

When wearing hearing aids, a mechanical interaction between the earmould and the skin of the outer ear canal occurs. The extent of this interaction, its influence on wearing comfort and long-term effects caused by continuously wearing a hearing aid are largely unknown. To quantify this interaction we develop a measurement system to measure the mechanical point impedance inside the human ear...

A unified three-dimensional high-order finite-element framework is proposed for the frequency-response analysis of finite layered acoustic systems under plane-wave and diffuse acoustic field (DAF) excitation. The formulation relies on factorized high-order expansions of the Carrera Unified Formulation (CUF) type. At the same time, the present benchmark focuses on acousticized structures,...

Ageing water infrastructure that includes water and sewer pipes often suffers from defects which are difficult to detect with water industry state of the art techniques. Wall thinning or delamination (external/internal) in pipe walls provides a challenging boundary value problem in 3D cylindrical system. Non-contact low frequency acoustic methods offer robust and easy to deploy technology...

Air suspension modeling is critical for estimating the NVH characteristics of chassis modules and full vehicles. However, accurate analytical modeling remains challenging because air suspensions exhibit inherently nonlinear behavior, and their force transmissibility varies with excitation amplitude. In previous research, a modeling technique was developed to predict the component-level...

Polymer melt flow in injection moulding is a black box phenomenon. During the process, the access to the flow field inside the steel tool is limited while high temperatures and pressures occur. A small number of sensors can be placed and flow simulations help understanding the process with numerous sensitive material and process parameters.To gain additional information, the injection moulding...

Electric vehicle powertrains exhibit prominent tonal and structure borne noise components originating from power electronic modules and electromagnetic excitations. Although particle dampers have been widely investigated for vibration attenuation, their application in electric vehicle powertrains with respect to structure-borne acoustic radiation remains limited. To the authors’ knowledge,...

Noise mitigation is a challenging societal issue. To overcome the limitations of conventional sound-absorbing materials and classical Tuned Mass Oscillators for broadband low-frequency control, this work proposes the use of nonlinear absorbers, known as Nonlinear Energy Sinks (NES), with stiffness governed by a nonlinear law. The acousto-mechanical studied NES is made of a thin viscoelastic...

Optical fibers used in high-precision interferometric systems are highly sensitive to external mechanical deformations. These environmental perturbations induce unwanted optical phase shifts, which severely limit the stability of the system. Therefore, accurately predicting this strain-induced phase shift is critical for designing vibration-insensitive optical components. This work...
