This book was released on 2014 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of today's challenging engineering and scientific problems involve the response of nonlinear solid materials to high-rate dynamic loading. Accompanying hydrodynamic effects are crucial, where the shock-driven pressure dominates material response. In this work a hydrodynamic meshfree formulation is developed under the Lagrangian reproducing kernel particle method (RKPM) framework. The volumetric stress divergence is enhanced to capture the high-pressure shock response, and the deviatoric portion is retained to describe strength effects of the solid material. A shock modeling formulation for scalar conservation laws is first constructed. In the scalar formulation the reproducing kernel particle method is formulated to address two key shock modeling issues, that is, accurate representation of the essential shock physics and control of the numerical oscillations due to Gibbs phenomenon at the jump. This is achieved by forming a smoothed flux divergence under the meshfree stabilized conforming nodal integration (SCNI) framework, and then enriching the flux divergence with a Riemann solution. The Riemann-enriched flux divergence is embedded into a velocity corrector adaptively applied at the shock front. As a consequence the shock solution is locally corrected while the smooth solution away from the shock is unaffected. For shocks in solids, developments from the scalar formulation were extended to the Cauchy's equation of motion. Shock effects in solids are pressure dominated, so that the shock solution is enhanced through the volumetric stress divergence. The volumetric stress divergence correction is formulated using a Rankine-Hugoniot enriched Riemann solution that introduces the essential shock physics to the formulation. Oscillation control is introduced through the state and field variable approximations that utilize the Riemann problem initial conditions, and therefore non-physical numerical parameters and length scales required in the traditional artificial viscosity technique are avoided. Further, because the proposed method for oscillation control is linked to the essential physics, the two key issues for accurate shock modeling are addressed in a unified and consistent way. For the nonlinear solids formulation, several benchmark problems are solved and the numerical results are verified by comparison to experimental data or analytical solutions. A range of shock conditions are studied to show the versatility of the proposed method for modeling conditions ranging from weak elastic-plastic shocks to strong shocks generated by hypervelocity impact.

Book Synopsis An Introduction to Meshfree Methods and Their Programming by : G.R. Liu
Download or read book An Introduction to Meshfree Methods and Their Programming written by G.R. Liu and published by Springer Science & Business Media. This book was released on 2005-12-05 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: The finite difference method (FDM) hasbeen used tosolve differential equation systems for centuries. The FDM works well for problems of simple geometry and was widely used before the invention of the much more efficient, robust finite element method (FEM). FEM is now widely used in handling problems with complex geometry. Currently, we are using and developing even more powerful numerical techniques aiming to obtain more accurate approximate solutions in a more convenient manner for even more complex systems. The meshfree or meshless method is one such phenomenal development in the past decade, and is the subject of this book. There are many MFree methods proposed so far for different applications. Currently, three monographs on MFree methods have been published. Mesh Free Methods, Moving Beyond the Finite Element Method d by GR Liu (2002) provides a systematic discussion on basic theories, fundamentals for MFree methods, especially on MFree weak-form methods. It provides a comprehensive record of well-known MFree methods and the wide coverage of applications of MFree methods to problems of solids mechanics (solids, beams, plates, shells, etc.) as well as fluid mechanics. The Meshless Local Petrov-Galerkin (MLPG) Method d by Atluri and Shen (2002) provides detailed discussions of the meshfree local Petrov-Galerkin (MLPG) method and itsvariations. Formulations and applications of MLPG are well addressed in their book.
Book Synopsis Relativistic Hydrodynamics by : Luciano Rezzolla
Download or read book Relativistic Hydrodynamics written by Luciano Rezzolla and published by OUP Oxford. This book was released on 2013-09-26 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relativistic hydrodynamics is a very successful theoretical framework to describe the dynamics of matter from scales as small as those of colliding elementary particles, up to the largest scales in the universe. This book provides an up-to-date, lively, and approachable introduction to the mathematical formalism, numerical techniques, and applications of relativistic hydrodynamics. The topic is typically covered either by very formal or by very phenomenological books, but is instead presented here in a form that will be appreciated both by students and researchers in the field. The topics covered in the book are the results of work carried out over the last 40 years, which can be found in rather technical research articles with dissimilar notations and styles. The book is not just a collection of scattered information, but a well-organized description of relativistic hydrodynamics, from the basic principles of statistical kinetic theory, down to the technical aspects of numerical methods devised for the solution of the equations, and over to the applications in modern physics and astrophysics. Numerous figures, diagrams, and a variety of exercises aid the material in the book. The most obvious applications of this work range from astrophysics (black holes, neutron stars, gamma-ray bursts, and active galaxies) to cosmology (early-universe hydrodynamics and phase transitions) and particle physics (heavy-ion collisions). It is often said that fluids are either seen as solutions of partial differential equations or as "wet". Fluids in this book are definitely wet, but the mathematical beauty of differential equations is not washed out.

Download or read book Flowing Matter written by Federico Toschi and published by Springer Nature. This book was released on 2019-09-25 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book, published in the Soft and Biological Matter series, presents an introduction to selected research topics in the broad field of flowing matter, including the dynamics of fluids with a complex internal structure -from nematic fluids to soft glasses- as well as active matter and turbulent phenomena. Flowing matter is a subject at the crossroads between physics, mathematics, chemistry, engineering, biology and earth sciences, and relies on a multidisciplinary approach to describe the emergence of the macroscopic behaviours in a system from the coordinated dynamics of its microscopic constituents. Depending on the microscopic interactions, an assembly of molecules or of mesoscopic particles can flow like a simple Newtonian fluid, deform elastically like a solid or behave in a complex manner. When the internal constituents are active, as for biological entities, one generally observes complex large-scale collective motions. Phenomenology is further complicated by the invariable tendency of fluids to display chaos at the large scales or when stirred strongly enough. This volume presents several research topics that address these phenomena encompassing the traditional micro-, meso-, and macro-scales descriptions, and contributes to our understanding of the fundamentals of flowing matter. This book is the legacy of the COST Action MP1305 “Flowing Matter”.
