In the field of assessment methodologies, particular importance is given to Non-Destructive Testing Techniques, which aspire to achieve the highest number of information about materials and structures without altering their condition. Ultrasonic Testing exploits the transmission and reflection characteristics of mechanical waves with appropriate frequencies passing through the investigated item. ...

To better quantify the impact of the morphological and mechanical properties of the main constituents of the stratum corneum (SC, the outermost layer of the skin) on its overall mechanical behavior, we developed a biomechanical model of the SC at a cellular scale, based on in vitro morphological and mechanical data. The sensitivity analysis quantified the relative impact of the mechanical and ...

We show a new, favourable space-saving method to host a neutron polarizer in the iron-containing monochromator shielding of a time-of-flight spectrometer for cold neutrons. In this poster you can learn e.g., how to create a robust, homogeneous, rectangular magnetic field (here realized by permanent magnet queues inside an iron tube). The time-of-flight spectrometer FOCUS at the spallation ...
Studying the Sensitivity of the Wrinkling Process to Mesh Imperfections Using COMSOL Multiphysics® and LiveLink™ for MATLAB®

Wrinkles are formed on a thin film as a result of buckling-based instabilities. This can be used as an inexpensive fabrication technique for generating micro and nano scale periodic patterns. Finite element techniques are used for the predictive design of complex wrinkling patterns. As wrinkles are formed via a bifurcation process, the accuracy of these models is dependent on the initial ...

The use of numerical techniques in PEM fuel cell sensoring represents an advantage of project engineering, reducing the costs and accelerating the manufacturing of prototypes. In this work some numerical responses are shown, relating to numerical sensoring of water and oxygen mole fractions at cathode of a 5 cm² of geometric area PEM fuel cell. The need to recognize a geometric figure of merit ...

This study is to investigate the velocity pattern and the velocity magnitude of the cuttings that is being processed in the process mill as a result of the rotating hammers. The process mill consists of a horizontal cylindrical shell equipped with renewable liners and rotating hammers for milling of drill cuttings. An F.E model of the process mill was constructed using dimensions similar to ...
Modeling and Simulation of High Sensitivity CMOS Pressure Sensor Using Free Boundary Circular Diaphragm Embedded on Ring Channel Shaped MOSFET

Sensors have diverse applications ranging from medical field to space explorations. They convert physical parameters such as temperature, pressure, humidity etc: - into an electrical output. The discovery of piezoresistivity property of silicon and germanium led to miniaturization of pressure sensors. Improvement in the sensitivity is the major factor to be considered while designing pressure ...

3D printing as applied to the area of electronics manufacture covers a broad range of traditional printing technologies . The attraction in 3D printing lies in its potential to disrupt the traditional photolithographic/subtractive manufacturing line with simpler additive processes. Additive electronics manufacturing which utilises 3D printing techniques allow for fewer production steps and ...

Fluid-structure interaction (FSI) refers to a class of problems in which the motions of fluid and solid are coupled. FSI is of great significance in many applications such as aero-elasticity, biomechanics, and design of various engineering systems. Typically, the multiphysics involved in the FSI problems render them too complex to solve analytically, necessitating the use of numerical ...

The successful implementation of a high-efficient latent heat storage system necessitates an appropriate experimental approach to investigate and quantify the variations of the Phase Change Material (PCM) thermal properties caused by its aging, as well as its potential demixing induced by cyclic freezing and melting. In this paper, we present a concept for the PCM characterization. The proposed ...
