The distinct element method

In this study, three-dimensional crystal plasticity finite element method (CPFEM) simulations of the nanoindentation test on zinc single crystal have been implemented in the finite element code Abaqus using a user material subroutine. The basics of deformation mechanisms of zinc, nanoindentation test and crystal plasticity theory will be presented.

The article presents numerical simulation results for tunnel collapse prediction using the Disctinct Element Method (DEM). The results of the study show that the use of DEM enables simulation of the collapse mechanism and prediction of its potential collapse extent in underground tunnel construction. Based on the simulation results, suitable measures to prevent a possible collapse could be proposed and planned.

The most distinctive property of ferromagnetism is the observation of hysteresis loops. It is the feature showing the fact that ferromagnetism can remain as a nonzero magnetization after applying an external field and then removing it. This paper aims to introduce one method of using finite element methodology to calculate demagnetization energy, hence to obtain the optimal configuration of magnetic material.

Alternative cleavage and polyadenylation (APA), an RNA processing event, occurs in over 70% of human protein-coding genes. APA results in mRNA transcripts with distinct 3′ ends. Most APA occurs within 3′ UTRs, which harbor regulatory elements that can impact mRNA stability, translation, and localization.

The distinct phases are separated by the interfaces represented by connected elements. So, there is a three-junction point among three phases: solid, liquid, and gas. The water droplets are assumed as a spherical cap and placed on the cold plate which is kept at a subfreezing temperature. At the end of solidification, we obtain a small protrusion shape at the top of the frozen water droplet and its height is also higher than that of the initial water droplet.

In this paper, vibration of a 2D-FGSW Timoshenko beam formed from three distinct materials traversed by a harmonic load is studied by the finite element method. The beam consists of three layers, a homogeneous core and two FGM skin layers with the material properties continuously varying in both the thickness and length directions by power functions.

In this paper, free vibration of bidirectional functionally graded sandwich (BFGSW) beams is studied by using a finite element formulation. The beams made from three distinct materials are composed of three layers, a homogeneous core and two bidirectional FGM face layers with material properties varying in both the thickness and longitudinal directions by power gradation laws. Based on the first-order shear deformation theory, a finite element formulation is derived and employed to compute the vibration characteristics of the beams with various boundary conditions.

Protein or nucleic acid sequences contain a multitude of associated annotations representing continuous sequence elements (CSEs). Comparing these CSEs is needed, whenever we want to match identical annotations or integrate distinctive ones.

Foreword For people who advocate and recognise the latent healing power of nature like my esteemed friend and fellow practitioner, Shri H.K. Bakhru, naturopathy is a way of life. It is a distinct philosophy and science which strengthens the age-old faith in the correction of bodily disorders and restoration and main- tenance of health through elements freely available in nature. It brings home the basic fact that healing is brought about by the inherent curative powers of the body. The simplicity of this method should not deter individuals from its use.

The distinction between science, engineering and technology is not always clear. Science is the reasoned investigation or study of phenomena, aimed at discovering enduring principles among elements of the phenomenal world by employing formal techniques such as the scientific method.[13] Technologies are not usually exclusively products of science, because they have to satisfy requirements such as utility, usability and safety.

This book is about graphic design rather than being a book of graphic design. The distinction may seem slight, but it is fundamental to this volume as it covers the graphic design industry and its processes rather than simply functioning as a coffee-table book. However, this book also contains works from highly imaginative creatives, which are used to illustrate the fundamental principles and working methods that graphic designers employ in their day-to-day activities
