Ultrasonic nondestructive testing (NDT) is extensively used in fields like medicine, oil and gas, and aerospace to inspect materials without causing damage. However, developing experimental setups and prototypes can be costly and time-consuming. This study employs advanced computational ... 詳細を見る

Problem - The occlusion effect is an increase in loudness (sound pressure level) of your internal voice, especially in the low frequency range. Also, self-generated sounds such as chewing, swallowing, walking or running are amplified when the ears are blocked or occluded. Occlusion ... 詳細を見る

Electret condenser microphones are one of the most used transducers for a variety of applications. The engineer designing these cartridges must take into consideration many factors to create a design that meets its specifications. Most parts of the design have multiple constraints across ... 詳細を見る

We have recently published the discovery of avoided crossings present in the spectrum of freely vibrating rectangular thin plates(1). In this poster we show how the Structural Mechanics module of COMSOL Multiphysics was a fundamental tool to accomplish this feat, by easily generating ... 詳細を見る

Electrothermal actuators convert an electrical signal into a mechanical signal via Joule heating. Due to their simplicity and reliability, electrothermal actuators are commonly used in various fields across length scales: from human-scale soft robotics to nanometer-scale sensors. We ... 詳細を見る

Introduction: The endothelial cells (ECs) in the blood brain barrier (BBB) are disrupted with age, genetic predisposition, or stroke and can lead to vascular cognitive impairment and dementia (VCID). Current treatments involve opening the BBB with high-frequency-ultrasound to deliver ... 詳細を見る

Excessive vent noise poses a prevalent challenge in various acoustic applications, significantly impacting the performance and user satisfaction of audio systems. This research investigates the efficacy of noise reduction using a lumped speaker model implemented in COMSOL Multiphysics. ... 詳細を見る

In diatomic molecules, the anti-bonding eigenstate is the higher energy state as the chemical bond is weakened between the two atoms due to the destructive interference of electronic wavefunctions. It is counterintuitive for the anti-bonding state to have lower energy given the bonding ... 詳細を見る

Polymers are increasingly used in many sectors, including consumer products and electronics, automotive and aerospace industries, medical devices and biopharma, and clean energy and batteries. These industries extensively use Multiphysics simulation to predict product performance, ... 詳細を見る

Nondestructive inspection (NDI) of damages (e.g., imperfect or degraded bonding lines) or the remaining strength of adhesively bonded lap joints is critical for the operational safety of aircrafts and vehicles. It remains a challenge to use the conventional NDI to quantitatively infer ... 詳細を見る
