Оля, хотя у Вас самые убедительные ссылки, но я подумал, что Вера все-таки первая "обнаружила" слово indentation и вариант indentation problem у нее был. Так что очки - ей.

die impression problem


Explanation:
Impression dies exist, but from the Russian wording it is more likely to be die impression problem rather than impression die problem.

indentation problem (Hencky, 1923)


Explanation:

During the first quarter of the twentieth century, the basic concepts, such as the yield surfaces, flow rules, slip lines, and plastic friction appeared, principally in the works of von KЁўrmЁўn (1909), von Mises (1913), Hencky (1924), and Reuss (1930). An important milestone was the resolution of the torsional problem (NЁўdai, 1923) and indentation problem (Hencky, 1923; Prandtl, 1923). The materials science foundation of metal plasticity in the dislocation theory was laid by Taylor (1934) and others.
http://www.wiley.co.uk/inelastic/introduction.html.


Metal-forming processes that closely approximate plane-strain conditions (and for which slip-line theory can be used to generate upper bounds on the forming forces) include forging, indentation, and cutting of wide strips, as well as continuous processes such as extrusion, drawing and rolling.

In this way, ideal boundary conditions at the stamp areas existed up to a HENCKY strain of ln(L(t)/L0) = 2.2

A systematic method of determining stress fields and associated velocity fields in perfectly plastic bodies obeying the Mises (or Tresca) yield criterion in plane strain was developed in the 1920s by Prandtl, Hencky,
