內(nèi)容概要
本書是在中文專著《新型有限元淪》(2004年版)的基礎(chǔ)上補(bǔ)充了2004年于2008年期間的新成果所撰寫的英文專著,是龍馭球院士、岑松博士和龍志飛教授及具研究組多年來在新型有限元方面研究成果的系統(tǒng)論述。全書分為20章。除首尾兩章外,其余18章分為3篇:第1篇是變分原理進(jìn)展,介紹分區(qū)和含參變分原理2項(xiàng)成果;它們?yōu)闃?gòu)造新型有限元起到理論指導(dǎo)作用。第2篇是有限元法進(jìn)展初論,重點(diǎn)介紹廣義協(xié)調(diào)元;這是在協(xié)調(diào)元與非協(xié)調(diào)元之間另辟的新路,使協(xié)調(diào)問題和收斂問題得到合理解決,單元構(gòu)造方案可以靈活優(yōu)選,學(xué)科內(nèi)容得到充實(shí)更新;廣義協(xié)調(diào)元是新型有限元方面的主要成果,在本書中起核心作用。第3篇是有限元法進(jìn)展續(xù)論,補(bǔ)充介紹4項(xiàng)成果,包括分區(qū)混合元法、解析試函數(shù)法、第一和第二類四邊形面積坐標(biāo)法和樣條函數(shù)有限元法,在本書中起錦上添花作用。木書還結(jié)合7項(xiàng)成果的論述,介紹了總共108個(gè)相關(guān)的新單元。 本書可作為高等學(xué)校力學(xué)、土木、機(jī)械等專業(yè)研究生和高年級(jí)本科生的教材和參考書,也可供相關(guān)領(lǐng)域教師和科技人員參考。
