Mechanics and Analysis of Composite Materials - Original PDF
نویسندگان: خلاصه: This book is concerned with the topical problems of mechanics of advanced composite materials whose mechanical properties are controlled by high-strength and high-stiffness continuous fibers embedded in polymeric, metal, or ceramic matrix. Although the idea of combining two or more components to produce materials with controlled properties has been known and used from time immemorial, modern composites have been developed only several decades ago and have found by now intensive application in different fields of engineering, particularly, in aerospace structures for which high strength-to-weightand stiffnessto-weight ratios are required.
Quantum thermodynamics: emergence of thermodynamic behavior within composite quantum systems - Original PDF
نویسندگان: خلاصه: This extended tutorial essay views thermodynamics as an incomplete description of quantum systems with many degrees of freedom. The main goal is to show that the approach to equilibrium - with equilibrium characterized by maximum ignorance about the open system of interest - neither requires that many particles nor is it a precise way of partitioning relevant for the salient features of equilibrium and equilibration. Moreover it is indeed quantum effects that are at work in bringing about universal thermodynamic behaviour of modestly sized open systems. Von Neumann`s concept of entropy thus proves to be much more widely useful than something to be feared, and far beyond truly macroscopic systems in equilibrium.
