內容簡介
Nonlinear Deformable-body Dynamics mainly consists in a mathematical treatise of approximate theories for thin deformable bodies,including cables,beams,rods,webs,membranes,plates,and shells.The intent of the book is to stimulate more researches in the area of nonlinear deformable-body dynamics not only because of the unsolved theoretical puzzles it presents but also because of its wide spectrum of applications.For instance,the theories for soft webs and rod-reinforced soft structures can be applied to biomechanics for DNA and living tissues,and the nonlinear theory of deformable bodies,based on the Kirchhoff assumptions,is a special case discussed.This book can serve as a reference work for researchers and a textbook for senior and postgraduate students in physics,mathematics,engineering and biophysics.

前言/序言
Deformable-body dynamics is a subject to investigate the states of strains and internal relative motions in deformable solids subject to the action of external forces.This is all old and interesting topic.and many problems still are unsolved or solved incompletely.Rethinking such problems in this topic may bring new vital to the modern science and technology.The first consideration of the nature of the resistance of deformable-bodies to rupture was given by Galileo in 1638.The theory of deformable.bodies.started from Galileos problem.is based on the discovery of Hookes Law in 1660 and the general differential equations of elasticity by Navier in 1821.The HookeS law is an experimental discovery about the stress and strain relation.This law provides the basis to develop the mathematical theory 0f deformable bodies.In 1821.Navier was the first to investigate the general equations of equilibrium and vibration of elastic solids.In 1850.Kirchhoff proposed two assumptions:(i)that linear filaments Of the plate initially normal to the middle.surface remain straight and normal to the middle.surface after deformed.and (ii) that all fibers in middle surface remain unstretched.Based on the Kirchhoff assumptions,the approximate theories for beams,rods,plates and shells have been developed for recent 1 50 years.From the theory of 3.dimensional de.formable body.with certain assumptions.this book will present a mathematical treatise of such approximate theories for thin deformable.bodies including cables.beams,rods,webs,membranes,plates and shells.The nonlinear theory for de.formable body based on the Kirchhoff assumptions is a special case to be discussed.This book consists of eight chapters.Chapter 1 discusses the history Of the deformable body dynamics.Chapter 2 presents the mathematical tool for the de.formation and kinematics of deformable.bodies.Chapter 3 addresses the deformation geometry.kinematics and dynamics of deformable body.Chapter 4 discusses constitutive laws and damage theory for deformable-bodies.In Chapter 5.nonlinear dynamics of cables is addressed.Chapter 6 discusses nonlinear plates and waves,and the nonlinear theories for webs,membranes and shells are presented in Chapter 7.Finally,Chapter 8 presents the nonlinear theory for thin beams and rods.
好的,這是一份關於另一本假想圖書的詳細簡介,其主題與《非綫性變形體動力學》無關。 --- 圖書簡介: 《古老的迷航:拜占庭帝國邊疆的絲綢之路貿易與文化交融》 作者: 艾麗西亞·瓦倫丁 (Alicia Valentein) 齣版社: 普羅米修斯學術齣版社 齣版年份: 2023年 --- 內容概述: 《古老的迷航:拜占庭帝國邊疆的絲綢之路貿易與文化交融》是一部深入考察拜占庭帝國(東羅馬帝國)在其漫長曆史中,尤其是在其東部和東北部邊疆地區,與橫跨歐亞大陸的絲綢之路沿綫文明進行復雜互動的裏程碑式著作。本書並非聚焦於帝國的軍事戰略或核心的基督教神學,而是將目光投嚮瞭帝國邊緣地帶的日常經濟活動、商品流動、信仰傳播以及由此産生的文化變遷。 作者艾麗西亞·瓦倫丁以其深厚的考古學、曆史地理學和早期中世紀經濟史知識為基礎,挑戰瞭長期以來將拜占庭視為一個相對封閉的、以君士坦丁堡為中心的實體這一傳統觀念。本書強調,拜占庭的繁榮與穩定在很大程度上依賴於其與波斯薩珊王朝、後來的伊斯蘭哈裏發國、中亞遊牧民族,乃至更東方的印度和中國之間的商業網絡。 全書結構清晰,分為六個主要部分,逐步構建瞭一個動態的、相互聯係的邊疆生態係統圖景。 第一部分:地理與製度的框架 本書開篇首先界定瞭“邊疆”的復雜性。作者摒棄瞭簡單的地理分界綫概念,而是將其視為一個充滿張力與機遇的過渡地帶。重點分析瞭安納托利亞東部、高加索地區和美索不達米亞北部這些關鍵的貿易樞紐。瓦倫丁細緻地描繪瞭查士丁尼大帝之後,拜占庭對這些地區進行的行政和財政重組——特彆是“主題製”(Theme System)的演變如何影響瞭地方精英與外部商人的關係。本部分通過對早期《馬吉斯特裏·奧菲西奧魯姆》(Magister Officiorum)的行政文件和海關記錄的重釋,揭示瞭國傢權力如何試圖規範和榨取穿過其疆域的商業財富。 第二部分:商品洪流:從絲綢到香料的經濟學 此部分是全書的核心經濟分析。瓦倫丁利用最新的同位素分析結果和考古齣土的貿易實物(包括陶器碎片、錢幣窖藏和玻璃製品),重建瞭關鍵貿易路綫的流量模型。書中詳細闡述瞭奢侈品(如來自中國的生絲、波斯的香料和印度寶石)如何進入帝國市場,以及帝國自身的優質産品(如底格裏斯河畔的羊毛、君士坦丁堡的精工金屬製品和葡萄酒)如何反嚮輸齣。 特彆引人注目的是作者對“白銀危機”時期的研究。在七世紀阿拉伯擴張導緻傳統貿易路綫受阻後,拜占庭邊疆經濟如何適應,轉嚮瞭以黃金(蘇利德)為基礎的內部循環,並開闢瞭更為依賴黑海和北方的斯拉夫-瓦蘭吉亞路綫的替代方案。這一分析對於理解拜占庭後期的經濟韌性至關重要。 第三部分:信仰的橋梁與障礙 貿易從來都是文化和信仰交流的載體。本書深刻探討瞭絲綢之路上不同宗教實踐在邊疆地區的共存與衝突。作者對敘利亞基督教(聶斯脫裏派)、亞美尼亞使徒教會、摩尼教、瑣羅亞斯德教以及逐漸興起的伊斯蘭教在拜占庭控製下的城鎮中的傳教活動進行瞭細緻的考察。 通過分析墓葬碑文、修道院記錄(如公元9世紀聖凱瑟琳修道院的信件)和圖像學證據,瓦倫丁展示瞭異教信仰如何通過與帝國商業精英的聯姻或閤作而得以維持,以及拜占庭官方教會如何在新興的宗教力量麵前采取瞭實用主義的容忍政策,而非一概的壓製。 第四部分:物質文化與身份重塑 本部分聚焦於日常生活中的文化融閤現象。作者考察瞭邊疆地區的建築風格、服飾偏好和飲食習慣的變化。例如,對卡帕多西亞的岩洞教堂壁畫中人物著裝風格的分析,揭示瞭拜占庭貴族如何采納瞭部分東方遊牧民族的服飾元素以示威嚴或實用性。 書中還首次係統地比較瞭帝國邊境城鎮與鄰近的阿拉伯或突厥聚落中齣土的玻璃器皿製作工藝。研究錶明,在某些時期,技術知識和熟練工匠的流動性極高,使得“拜占庭風格”和“東方風格”的界限變得模糊不清。 第五部分:遊牧民族的動態參與 瓦倫丁認為,拜占庭的邊疆並非是帝國與“野蠻人”的截然對立麵,而是一個充滿動態互動的區域。本書用大量篇幅描述瞭帝國如何通過“外交饋贈”(donativa)、雇傭兵製度以及有計劃的通婚,將保加爾人、馬紮爾人、阿蘭人乃至早期的突厥部落納入其經濟和政治體係。這些遊牧群體不僅是威脅,更是重要的中間商、邊境保護者和奢侈品消費者。通過解讀帝國編年史中對這些民族的描述與實際的貿易閤同對比,作者揭示瞭官方宣傳與邊疆現實之間的巨大鴻溝。 第六部分:遺産與曆史的再評價 最後一部分總結瞭絲綢之路貿易對拜占庭帝國長期存續的深遠影響。作者認為,正是這種適應性和對外部資源的有效整閤能力,使得帝國能夠在持續的軍事壓力下維持其經濟的完整性長達韆年。 《古老的迷航》的結論指齣,拜占庭帝國真正的生命力,不在於其宏偉的教堂或精妙的法律體係,而在於其邊疆地帶商人、工匠、外交官和教士們,在絲綢之路上進行的,復雜、務實且充滿變數的文化與物質交流。本書為研究中世紀地中海與亞洲之間的互動提供瞭一個全新的、極具啓發性的視角。 --- 目標讀者: 曆史學、考古學、中世紀研究、經濟史、以及對歐亞大陸交流史感興趣的學者和高級學生。
