作者簡介

前 言
2005年前后，清華大學(xué)工程力學(xué)系研究生課程“固體本構(gòu)關(guān)系”更名為“高等固體力學(xué)”，擴充了應(yīng)用性的內(nèi)容。
“高等固體力學(xué)”課程主要研究大變形問題，但作為基礎(chǔ)，本書上冊仍保留了第 1章“小變形彈塑性本構(gòu)關(guān)系”，因為這是一個力學(xué)工作者必須具備的基礎(chǔ)知識。如果不掌握小變形的理論，那么大變形的理論就無從談起。
研究大變形固體力學(xué)，需要兩方面的基礎(chǔ)：
（1）張量分析：目前多數(shù)教材中用到的張量分析知識還僅限于將張量當(dāng)作帶指標(biāo)的符號。實際上，張量分析的理論與用途遠(yuǎn)比指標(biāo)符號深刻得多。它不僅可以使推導(dǎo)變得十分簡潔，而且還可以清楚地顯示出問題本身的物理意義，有時用張量分析方法可以得到一些意想不到的結(jié)果。我們可以毫不夸張地說，不懂得張量分析，要閱讀和消化現(xiàn)代力學(xué)文獻是不可能的。清華大學(xué)工程力學(xué)系每年都為碩士生開設(shè)“張量分析”學(xué)位課 1)。
（2）連續(xù)介質(zhì)力學(xué)：包括應(yīng)力理論、應(yīng)變理論和本構(gòu)關(guān)系。如果缺少張量分析和連續(xù)介質(zhì)力學(xué)的知識，高等固體力學(xué)的講授就不可能達到足夠的深度。為此，上冊增加了附錄：張量分析（介紹）——當(dāng)然，其中只包含一些最少量的張量分析的必要知識；同時，上冊第 2章“連續(xù)介質(zhì)力學(xué)概述”介紹了研究固體力學(xué)所必需的連續(xù)介質(zhì)力學(xué)基礎(chǔ)知識。
上冊第 3章“大變形彈性本構(gòu)關(guān)系及應(yīng)用”講述大變形彈性本構(gòu)關(guān)系的理論、邊值問題的解法和一些典型問題的解；第 4章“大變形彈塑性本構(gòu)關(guān)系”系統(tǒng)介紹了許多基本概念和幾種主要的理論。對于大變形問題，本構(gòu)關(guān)系可以在物體變形前的構(gòu)形（參考構(gòu)形）中寫出，也可以在物體變形后的構(gòu)形（即時構(gòu)形）中寫出，甚至還可以在卸載后的構(gòu)形（中間構(gòu)形）中寫出。這幾種寫法涉及到不同的坐標(biāo)，不同的應(yīng)力（率）與不同的應(yīng)變（率）。驟然看來，它們之間的關(guān)系非常復(fù)雜?？紤]到這一難點，本書上冊著重說明這幾種寫法之間的相互“轉(zhuǎn)移”關(guān)系，希望讀者做到舉一就能反三。為了解決實際大變形問題，往往需要采用有限元方法計算。 ABAQUS是一個比較便利有效的計算軟件——上冊有一附錄，介紹該軟件的理論基礎(chǔ)。

高等固體力學(xué)（上冊）
以上內(nèi)容的初稿曾在清華大學(xué)研究生課程“高等固體力學(xué)”教學(xué)中試用五遍，幾經(jīng)修改定稿后，今作為本書上冊出版。
本書下冊討論介紹固體力學(xué)近二十年來幾個活躍的研究領(lǐng)域。
第 1章是“晶體的大變形彈塑性理論”。晶體是上冊第 4章大變形彈塑性本構(gòu)理論最適合的應(yīng)用對象，通過晶體塑性可以加深對理論的理解。
第 2章“應(yīng)變梯度塑性理論”論述微米尺度下的塑性理論。近年的試驗表明，當(dāng)材料的非均勻塑性變形特征長度在微米量級時，材料具有很強的尺度效應(yīng)。其原因在于：塑性應(yīng)變?yōu)榉蔷鶆驎r，塑性應(yīng)變梯度的存在導(dǎo)致“幾何必需位錯”產(chǎn)生，使屈服應(yīng)力（“流動應(yīng)力”）增大。因此，一點處的應(yīng)力不僅與該點處的應(yīng)變有關(guān)，而且也與該點處的塑性應(yīng)變梯度有關(guān)。由于經(jīng)典的塑性理論中材料本構(gòu)模型不包含任何尺度參數(shù)，所以它不能預(yù)測材料的尺度效應(yīng)。然而，隨著高技術(shù)的發(fā)展，在工程設(shè)計中迫切需要處理微米量級的設(shè)計和制造問題，例如：微電力系統(tǒng)（ MEMS）、微電子封裝、先進復(fù)合材料及微加工。因此現(xiàn)代工程設(shè)計需要微米尺度下的力學(xué)理論。
第 3章是“納米管的力學(xué)”。碳納米管具有優(yōu)良的力學(xué)特性，但過去被認(rèn)為由于屬納米尺度，不能采用連續(xù)介質(zhì)力學(xué)，而只能用分子動力學(xué)來進行分析計算。分子動力學(xué)的出發(fā)點是原子勢，第 3章論述如何直接從原子勢出發(fā)，建立納米管或者任意的納米曲面的連續(xù)介質(zhì)力學(xué)。
第 4章是“柔性可伸展電子元件的力學(xué)”。電子元件是由硅制成的。硅是易斷的脆性材料，其斷裂應(yīng)變只有 2%。第 4章研究利用“屈曲”現(xiàn)象制成可伸展電子元件（從而可大大提高電子元件的功能）的原理，分析結(jié)構(gòu)構(gòu)件過屈曲行為的力學(xué)方法，同時也發(fā)展了梁、板、殼的過屈曲理論。
本書所反映的研究成果得到了國家自然科學(xué)基金委重大和面上項目的長期支持，我們對此表示衷心的感謝；第二作者同時也感謝美國科學(xué)基金會的支持；另外，對海內(nèi)外的合作者、為本書出版過程提供過幫助的同事和學(xué)生，以及清華大學(xué)出版社長期的出版支持，我們一并在此致以誠摯的謝意!
