150th birthday anniversary of Maksymilian Tytus Huber
January 4 was the 150th birthday anniversary of Professor Maksymilian Tytus Huber (1872-1950), an outstanding representative of Polish mechanics. He formulated, among others, the hypothesis of material effort (1904), which is still commonly used in the theory of plasticity. In the world literature it is known as the von Mises condition, more rarely as the Huber-von Mises or Huber-von Mises-Hencky condition.
A biography of Professor Huber can be found, for example, at Wikipedia. His seminal 1904 paper, translated into English, has been published in Archives of Mechanics in 2004 [link].
