 Free Download Sic Itur ad Astra by Harold A. Skaarup English | September 13, 2024 | ISBN: 8887759448 | 496 Pages | epub | 35,96 MB  Free Download Shock-Wave Phenomena and the Properties of Condensed Matter By G. I. Kanel, V. E. Fortov, S. V. Razorenov (auth.) 2004 | 322 Pages | ISBN: 1441919163 | PDF | 19 MB Strong shock waves present unique opportunities for investigations in the fields of physics of condensed matter, thermophysics, physics of strength and plasticity, and chemical physics under conditions of the highest possible rates of deformation, and high pressures and temperatures. The physics of shock waves in condensed matter deal with pressures from ~100 MPa to several hundreds of GPa (and up to ten TPa in some unique experiments), temperatures up to tens of thousands of K, and durations of load application from nanoseconds to a few microseconds. Behavior of a material under these extreme conditions often differs radically from expectations based on quasistatic observations. As an example, observed anomalous temperature dependencies of the strength properties of some metals were not predicted by theories. The investigations of shock-wave phenomena in condensed matter that are discussed in this book are stimulated by the necessity to develop methods for predicting effects of explosions, high-velocity collisions, and other sources of intense dynamic loading of materials and structures. In the modern view, complete predictability is achieved when computers can accurately simulate processes of interest. The simulations require development of thermophysical equations of state and constitutive relationships that describe processes of inelastic deformation and fracture, polymorphic transformations, chemical reactions, melting, vaporization, ionization, and other phenomena observed under these conditions. Systematic discussions of various aspects of thermomechanical behavior of solid materials of different classes when subjected to shock-wave loading comprise the main part of this book. It provides an account of recent Russian work in this field that is unique in its balanced coverage of theoretical, experimental, and computational results. The discussions include a comprehensive analysis of:The structure of compression and rarefaction waves in solids, experimental data on the dynamic yield and tensile strengths of metals and alloys at normal and elevated temperatures, and constitutive relationships that describe high-rate yielding Static and dynamic compressive deformation and fracture of brittle materials, and failure-wave phenomena Shock induced polymorphic transformation, melting, and vaporization Explosive initiation and detonation phenomena, with emphasis on macrokinetics of chemical energy release Physics of the most extreme states of matter accessible by shock compression.
 Free Download Shock Waves @ Marseille IV: Shock Structure and Kinematics, Blast Waves and Detonations By L. F. Henderson (auth.), Professor Dr. Raymond Brun, Professor Dr. Lucien Z. Dumitrescu (eds.) 1995 | 505 Pages | ISBN: 364279534X | PDF | 23 MB This volume is devoted to the problems directly connected to the propagation of shock waves, blast waves and detonations and their interaction with various ctructures, gaseous, liquid or solid. Shock focusing is the first subject whereas regular or Mach reflection processes, shock wave refraction and diffraction on diverse configurations such as wedge, cone, or corner, represent central themes for many following papers. The well-known problem of shock-interface interaction still constitutes an attractive subject and a number of papers are devoted to shock-jet, shock-vortex, and shock-layer interactions. Explosions and blast waves studies are well represented, and detonation phenomena in gaseous, solid or multiphasic media are largely treated. The kinetic structure of shock itself is also analyzed.Scientists working in the fields of shock-structure interaction will be interested by the number and level of corresponding papers, and engineers may be attracted by the multiple applied aspects of shock, blast and detonation propagation.
 Free Download Shock Waves @ Marseille III: Shock Waves in Condensed Matter and Heterogeneous Media By M. E. H. van Dongen (auth.), Professor Dr. Raymond Brun, Professor Dr. Lucien Z. Dumitrescu (eds.) 1995 | 485 Pages | ISBN: 3642788378 | PDF | 14 MB This volume gathers papers treating effects of shock waves propagating in complex media, such as polyphasic and porous media, and in condensed matter: thus, two-phase flows with shock waves include dust and droplet gas suspensions, steam, bubbly liquids without or with evaporation or condensation. The second volume also includes papers devoted to industrial and environmental applications involving shock waves, and thus miscellaneous applied topics such as lasers, high-speed trains, car exhausts, and guns are concerned, as well as for environmental problems, volcanic eruptions, meteorite impacts, and orbital debris. Finally, biological aspects of shock waves are presented such as the effects on biliary and renal stones, cancerous tissues, and the pulmonary system.This volume addresses scientists working in the treated topics, such as multiphasic and porous media, and various categories of engineers or technicians, especially from both environmental and space technology, and medical personnel interested in biological effects and medical applications of shock waves.
 Free Download Shock Waves @ Marseille II: Physico-Chemical Processes and Nonequilibrium Flow By John H. Kiefer (auth.), Professor Dr. Raymond Brun, Professor Dr. Lucien Z. Dumitrescu (eds.) 1995 | 467 Pages | ISBN: 3642788343 | PDF | 18 MB This volume deals with chemical kinetics of high-temperature shocked flows. The first papers describe the kinetics of many processes in gases and gas mixtures behind shock waves in shock tubes, including decomposition, oxidation, dissociation and various reactions, with the general purpose of measuring corresponding rate constants by various diagnostic techniques. Other papers treat problems of induced combustion behind shock paves propagating in combustible media. Theoretical and experimental studies on nonequilibrium flows in external and internal aerodynamics, including vibrational relaxation, dissociation and reaction kinetics and radiation effects, and the analysis of ionization phenomena induced by shock waves and of the behavior of shock waves in ionized media such as plasma jets, discharges or magnetic fields are represented.This volume is for chemists and chemical engineers working in reaction kinetics and combustion fields, plasma physicists, astrophysicists and also aerodynamicists simulating or computing relaxing reactive flows.

Dumitrescu (eds.) 1995 | 485 Pages | ISBN: 3642788319 | PDF | 15 MB The book is devoted to hypersonics, including experimental work in shock tunnel flows with emphasis on the influence of "real gas" effects on aerodynamic phenomena encountered in hypersonics and aerospace studies. Numerical methods used for the determination of hypersonic flowfields, including chemical effects, are presented and applied to steady and unsteady configurations. The book also contains recent progress in shock tube and shock tube tunnel technology, including free piston shock tunnels, diaphragmless shock tubes, various processes for improving shock tube performances and numerous diagnostic techniques used in millisecond facilities such as force, moment measurements and optical methods. Papers on mixing problems in supersonic combustion and applications to ram accelerators are also in this volume. This volume is addressed to scientists working on "hot" hypersonics, aerospace engineers, shock tube designers, researchers using shock tubes and associated equipment, and CFD people trying to simulate complex reactive flowfields.

Free Download Shielding Your Spirit: Navigating Life with Pessimistic People by bright days English | October 29, 2024 | ISBN: N/A | ASIN: B0DLDR7F5M | 91 pages | EPUB | 0.83 Mb Pessimism is a mindset characterized by a tendency to focus on the negative aspects of situations, anticipating unfavorable outcomes and often expressing doubt or skepticism about the future. This outlook can manifest in various ways, from subtle commentary on everyday events to overt expressions of despair about life's direction. Understanding the essence of pessimism is crucial for adults who navigate relationships with pessimistic individuals, as the pervasive nature of this outlook can significantly impact emotional well-being and interpersonal dynamics. Recognizing that pessimism often stems from past experiences, disappointments, and fears can help us approach these interactions with empathy, even as we set necessary boundaries.
