We start this third issue of volume 100 with a re‐publication from 1924:

Heinrich Hencky ‐ Zur Theorie plastischer Deformationen und der hierdurch im Material hervorgerufenen Nachspannungen (ZAMM 4:323–334).

This work is first translated into English and then discussed.

The scientific life of Heinrich Hencky was not always straightforward, seeing as he was struggling with different adversities his entire lifetime. During the 1920s of the last century, he published some fundamental papers in the ZAMM. Unfortunately, these articles were written in German which was the scientific language of mathematics, mechanics and engineering back those days. We hope that the non‐German speaking community, with help of the translation, will get a more detailed insight in fundamental problems of that time and Hencky's ideas to solve them.

Heinrich Hencky (∗November 2, 1885, in Ansbach, Bavaria, Germany; †July 6, 1951, in Gries, Tyrol, Austria) was a German engineer who made considerable contributions to plasticity, continuum mechanics, and plate theory among others. He studied civil engineering at the Technische Hochschule Munich. In 1912, he moved to the Technische Hochschule in Darmstadt as “design engineer and assistant for engineering sciences” and received his doctorate in 1913 with a thesis on the numerical calculation of stresses in thin plates. In 1914, he was employed as a railway engineer in Kharkov (Russian Empire). His career was terminated during World War I after which he returned to Germany. His plan to regain foothold as a test engineer in Warnemünde in a project for a seaplane failed because of the general demobilization of Germany. In 1919, Hencky returned to the Technische Hochschule Darmstadt and in 1920, he moved to Dresden. He wrote his habilitation on stability problems of elastic structures which he defended in 1921. After that, he was looking for a permanent position: at first in Germany, later in the Netherlands (Technical University of Delft) and in the USA (MIT in Cambridge, Massachusetts). His last contract ended in 1932. Subsequently, he tried to survive as a farmer ‐ with occasional contracts as a consultant. After 3 years, he was invited by Boris G. Galerkin and Hencky accepted a position as professor for Engineering Mechanics at the Kharkov Polytechnic Institute and later at the Institute of Mechanics of Lomonosov University in Moscow headed by Alexei A. Ilyushin. Here he improved the Soviet Union lightweight (airplane) construction by applying his deformation theory. In 1938, he and his family were sent back to Germany and he could find a position at MAN Company in Gustavsburg.

社论

我们从1924年开始重新出版,从第100卷的第三期开始:

海因里希·亨基·祖尔(Heinrich Hencky-Zur)理论在材料上的变形和变迁(ZAMM 4:323–334)

这项工作首先被翻译成英文,然后再进行讨论。

海因里希·亨基(Heinrich Hencky)的一生并不总是一帆风顺,因为他一生都在努力应对各种逆境。在上世纪1920年代,他在ZAMM上发表了一些基础论文。不幸的是,这些文章都是用德语写的,当时的德语是数学,力学和工程学的科学语言。我们希望说非德语的社区在翻译的帮助下,能够更详细地了解当时的基本问题以及Hencky解决这些问题的想法。

海因里希·亨基(Heinrich Hencky,1885年11月2日在德国巴伐利亚州安斯巴赫; 1951年7月6日在奥地利蒂罗尔州格里斯)是一位德国工程师,在可塑性,连续体力学和板理论等方面做出了巨大贡献。他在慕尼黑理工大学学习土木工程。1912年,他以“设计工程师和工程科学助理”的身分前往达姆施塔特理工大学,并于1913年获得博士学位,其论文涉及薄板应力的数值计算。1914年,他受聘为哈尔科夫(俄罗斯帝国)的铁路工程师。第一次世界大战结束了他的职业生涯,此后他回到了德国。由于德国的全面复员,他在瓦尔内明德(Warnemünde)的一个水上飞机项目中重新成为测试工程师的计划失败了。在1919年,汉基(Hencky)返回达姆施塔特理工大学(Danis),并于1920年移居德累斯顿。他写了关于弹性结构稳定性问题的动手能力,并于1921年辩护。此后,他一直在寻找一个永久性职位:首先是在德国,后来在荷兰(代尔夫特技术大学)和美国(在麻省理工学院的剑桥) ,马萨诸塞州)。他的最后一份合同于1932年结束。随后,他试图以农民的身份生存-偶尔担任顾问。3年后,他应鲍里斯·加勒金(Boris G. Galerkin)的邀请,汉基(Hencky)担任了哈尔科夫理工学院的工程力学教授,随后又在以阿列克谢·伊柳申为首的莫斯科罗蒙诺索夫大学力学学院任职。在这里,他通过运用变形理论改进了苏联的轻型(飞机)结构。
