A new model to solve fluid–hypo-elastic solid interaction using the smoothed particle hydrodynamics (SPH) method

Abstract: Adaptability is the most attractive feature of the smoothed particle hydrodynamics (SPH) method. Therefore it can naturally handle problems with extremely large deformation. Fluid–structure interaction (FSI) problems are placed in this category. In FSI problems, using a good contact algorithm is necessary to achieve fidelity of the results. This paper presents a new numerical simulation based on the SPH method for FSI problems. The main contribution of this work is proposing new algorithms to model the contact between a viscous fluid and hypo-elastic solid particles. In the proposed contact model, the interpenetrations of fluid and solid particles are prevented by introducing a repulsive force and new intermediate particles. The validity of the proposed algorithms is verified, and in order to show their ability several examples are solved.

Introduction to the Finite Element Method

Abstract: This chapter introduces the finite element method (FEM) as a tool for solution of classical electromagnetic problems. Although we discuss the main points in the application of the finite element method to electromagnetic design, including formulation and implementation, those who seek deeper understanding of the finite element method should consult some of the works listed in the bibliography section.

A review of energy harvesting using piezoelectric materials: state-of-the-art a decade later (2008–2018)

Abstract: Energy harvesting technologies have been explored by researchers for more than two decades as an alternative to conventional power sources (e.g. batteries) for small-sized and low-power electronic devices. The limited life-time and necessity for periodic recharging or replacement of batteries has been a consistent issue in portable, remote, and implantable devices. Ambient energy can usually be found in the form of solar energy, thermal energy, and vibration energy. Amongst these energy sources, vibration energy presents a persistent presence in nature and manmade structures. Various materials and transduction mechanisms have the ability to convert vibratory energy to useful electrical energy, such as piezoelectric, electromagnetic, and electrostatic generators. Piezoelectric transducers, with their inherent electromechanical coupling and high power density compared to electromagnetic and electrostatic transducers, have been widely explored to generate power from vibration energy sources. A topical review of piezoelectric energy harvesting methods was carried out and published in this journal by the authors in 2007. Since 2007, countless researchers have introduced novel materials, transduction mechanisms, electrical circuits, and analytical models to improve various aspects of piezoelectric energy harvesting devices. Additionally, many researchers have also reported novel applications of piezoelectric energy harvesting technology in the past decade. While the body of literature in the field of piezoelectric energy harvesting has grown significantly since 2007, this paper presents an update to the authors' previous review paper by summarizing the notable developments in the field of piezoelectric energy harvesting through the past decade.

Handbook Of Modern Sensors Physics Designs And Applications

Abstract: Thank you for reading handbook of modern sensors physics designs and applications. As you may know, people have search hundreds times for their chosen readings like this handbook of modern sensors physics designs and applications, but end up in infectious downloads. Rather than reading a good book with a cup of coffee in the afternoon, instead they juggled with some malicious bugs inside their laptop.
