内容简介
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,这是一份关于另一本假想图书的详细简介,其主题与《非线性变形体动力学》无关。 --- 图书简介: 《古老的迷航:拜占庭帝国边疆的丝绸之路贸易与文化交融》 作者: 艾丽西亚·瓦伦丁 (Alicia Valentein) 出版社: 普罗米修斯学术出版社 出版年份: 2023年 --- 内容概述: 《古老的迷航:拜占庭帝国边疆的丝绸之路贸易与文化交融》是一部深入考察拜占庭帝国(东罗马帝国)在其漫长历史中,尤其是在其东部和东北部边疆地区,与横跨欧亚大陆的丝绸之路沿线文明进行复杂互动的里程碑式著作。本书并非聚焦于帝国的军事战略或核心的基督教神学,而是将目光投向了帝国边缘地带的日常经济活动、商品流动、信仰传播以及由此产生的文化变迁。 作者艾丽西亚·瓦伦丁以其深厚的考古学、历史地理学和早期中世纪经济史知识为基础,挑战了长期以来将拜占庭视为一个相对封闭的、以君士坦丁堡为中心的实体这一传统观念。本书强调,拜占庭的繁荣与稳定在很大程度上依赖于其与波斯萨珊王朝、后来的伊斯兰哈里发国、中亚游牧民族,乃至更东方的印度和中国之间的商业网络。 全书结构清晰,分为六个主要部分,逐步构建了一个动态的、相互联系的边疆生态系统图景。 第一部分:地理与制度的框架 本书开篇首先界定了“边疆”的复杂性。作者摒弃了简单的地理分界线概念,而是将其视为一个充满张力与机遇的过渡地带。重点分析了安纳托利亚东部、高加索地区和美索不达米亚北部这些关键的贸易枢纽。瓦伦丁细致地描绘了查士丁尼大帝之后,拜占庭对这些地区进行的行政和财政重组——特别是“主题制”(Theme System)的演变如何影响了地方精英与外部商人的关系。本部分通过对早期《马吉斯特里·奥菲西奥鲁姆》(Magister Officiorum)的行政文件和海关记录的重释,揭示了国家权力如何试图规范和榨取穿过其疆域的商业财富。 第二部分:商品洪流:从丝绸到香料的经济学 此部分是全书的核心经济分析。瓦伦丁利用最新的同位素分析结果和考古出土的贸易实物(包括陶器碎片、钱币窖藏和玻璃制品),重建了关键贸易路线的流量模型。书中详细阐述了奢侈品(如来自中国的生丝、波斯的香料和印度宝石)如何进入帝国市场,以及帝国自身的优质产品(如底格里斯河畔的羊毛、君士坦丁堡的精工金属制品和葡萄酒)如何反向输出。 特别引人注目的是作者对“白银危机”时期的研究。在七世纪阿拉伯扩张导致传统贸易路线受阻后,拜占庭边疆经济如何适应,转向了以黄金(苏利德)为基础的内部循环,并开辟了更为依赖黑海和北方的斯拉夫-瓦兰吉亚路线的替代方案。这一分析对于理解拜占庭后期的经济韧性至关重要。 第三部分:信仰的桥梁与障碍 贸易从来都是文化和信仰交流的载体。本书深刻探讨了丝绸之路上不同宗教实践在边疆地区的共存与冲突。作者对叙利亚基督教(聂斯脱里派)、亚美尼亚使徒教会、摩尼教、琐罗亚斯德教以及逐渐兴起的伊斯兰教在拜占庭控制下的城镇中的传教活动进行了细致的考察。 通过分析墓葬碑文、修道院记录(如公元9世纪圣凯瑟琳修道院的信件)和图像学证据,瓦伦丁展示了异教信仰如何通过与帝国商业精英的联姻或合作而得以维持,以及拜占庭官方教会如何在新兴的宗教力量面前采取了实用主义的容忍政策,而非一概的压制。 第四部分:物质文化与身份重塑 本部分聚焦于日常生活中的文化融合现象。作者考察了边疆地区的建筑风格、服饰偏好和饮食习惯的变化。例如,对卡帕多西亚的岩洞教堂壁画中人物着装风格的分析,揭示了拜占庭贵族如何采纳了部分东方游牧民族的服饰元素以示威严或实用性。 书中还首次系统地比较了帝国边境城镇与邻近的阿拉伯或突厥聚落中出土的玻璃器皿制作工艺。研究表明,在某些时期,技术知识和熟练工匠的流动性极高,使得“拜占庭风格”和“东方风格”的界限变得模糊不清。 第五部分:游牧民族的动态参与 瓦伦丁认为,拜占庭的边疆并非是帝国与“野蛮人”的截然对立面,而是一个充满动态互动的区域。本书用大量篇幅描述了帝国如何通过“外交馈赠”(donativa)、雇佣兵制度以及有计划的通婚,将保加尔人、马扎尔人、阿兰人乃至早期的突厥部落纳入其经济和政治体系。这些游牧群体不仅是威胁,更是重要的中间商、边境保护者和奢侈品消费者。通过解读帝国编年史中对这些民族的描述与实际的贸易合同对比,作者揭示了官方宣传与边疆现实之间的巨大鸿沟。 第六部分:遗产与历史的再评价 最后一部分总结了丝绸之路贸易对拜占庭帝国长期存续的深远影响。作者认为,正是这种适应性和对外部资源的有效整合能力,使得帝国能够在持续的军事压力下维持其经济的完整性长达千年。 《古老的迷航》的结论指出,拜占庭帝国真正的生命力,不在于其宏伟的教堂或精妙的法律体系,而在于其边疆地带商人、工匠、外交官和教士们,在丝绸之路上进行的,复杂、务实且充满变数的文化与物质交流。本书为研究中世纪地中海与亚洲之间的互动提供了一个全新的、极具启发性的视角。 --- 目标读者: 历史学、考古学、中世纪研究、经济史、以及对欧亚大陆交流史感兴趣的学者和高级学生。
