Query: The axiomatic deduction of the quadratic Hencky strain energy by
  Heinrich Hencky   The introduction of the quadratic Hencky strain energy based on the
logarithmic strain tensor log V is a milestone in the development of nonlinear
elasticity theory in the first half of the 20th century. Since the original
manuscripts are written in German, they are not easily accessible today.
However, we believe that the deductive approach taken by Hencky deserves to be
rediscovered today. In this work we have gathered parts of the original
contributions "\"Uber die Form des Elastizit\"atsgesetzes bei ideal elastischen
Stoffen", "Welche Umst\"ande bedingen die Verfestigung bei der bildsamen
Verformung von festen isotropen K\"orpern?" and "Das Superpositionsgesetz eines
endlich deformierten relaxationsf\"ahigen elastischen Kontinuums und seine
Bedeutung f\"ur eine exakte Ableitung der Gleichungen f\"ur die z\"ahe
Fl\"ussigkeit in der Eulerschen Form" which center around this deductive
approach. We tried to provide, for the first time, a faithful translation into
English. All footnotes are our addition.
