商品描述

"During the last two decades, research on structural optimization became increasingly concerned with two aspects: the application of general numeri cal methods of optimization to structural design of complex real structures, and the analytical derivation of necessary and sufficient conditions for the optimality of broad classes of comparatively simple and more or less ideal ized structures. Both kinds of research are important: the first for obvious reasons; the second, because it furnishes information that is useful in testing the validity, accuracy and convergence of numerical methods and in assess ing the efficiency of practical designs. (Prager and Rozvany, 1977a) The unexpected death of William Prager in March 1980 marked, in a sense, the end of an era in structural mechanics, but his legacy of ideas will re main a source of inspiration for generations of researchers to come. Since his nominal retirement in the early seventies, Professor and Mrs. Prager lived in Savognin, an isolated alpine village and ski resort surrounded by some of Switzerland's highest mountains. It was there that the author's close as sociation with Prager developed through annual pilgrimages from Australia and lengthy discussions which pivoted on Prager's favourite topic of struc tural optimization. These exchanges took place in the picturesque setting of Graubunden, on the terrace of an alpine restaurant overlooking snow-capped peaks, on ski-lifts or mountain walks, or during evening meals in the cosy hotels of Savognin, Parsonz and Riom.

商品描述(中文翻譯)

在過去的二十年中,結構優化的研究越來越關注兩個方面:將一般數值優化方法應用於複雜實際結構的結構設計,以及對相對簡單且或多或少理想化的結構的最優性進行必要和充分條件的分析推導。這兩種研究都是重要的:第一種顯而易見;第二種則因為它提供了有用的信息,以測試數值方法的有效性、準確性和收斂性,並評估實際設計的效率。(Prager 和 Rozvany, 1977a)威廉·普拉格(William Prager)於1980年3月意外去世,在某種意義上標誌著結構力學的一個時代的結束,但他所留下的思想遺產將成為未來幾代研究者的靈感來源。自從七十年代初名義上退休以來,普拉格教授和他的妻子一直住在薩沃尼(Savognin),這是一個孤立的阿爾卑斯山村和滑雪度假勝地,四周環繞著瑞士最高的山脈。在那裡,作者與普拉格的密切關係通過每年從澳大利亞的朝聖之旅和長時間的討論而發展,這些討論圍繞著普拉格最喜愛的主題——結構優化。這些交流發生在格勞賓登(Graubunden)如畫的環境中,在一個俯瞰雪山的阿爾卑斯餐廳的露台上,或在滑雪纜車上、山間散步時,或在薩沃尼、帕爾松茲(Parsonz)和里奧姆(Riom)舒適的酒店中享用晚餐時。
