 Russian term or phrase: дифракция упругой волны сдвига на полубесконечном дефекте No context to speak of... It's the title of a thesis, the character is a mathematician.
 Diffraction of elastic shear wave by a semi-infinite crack/imperfection Explanation:дифракция = diffraction упругая волна сдвига = elastic shear wave (СДВИГОВАЯ ВОЛНА, поперечная упругая волна, распространяющаяся в твердом теле и вызывающая деформацию сдвига, смещения частиц в которой перпендикулярны направлению ее распространения). I failed to find any "shift wave" or "wave of shift" in any available dictionary. But there are many examples of "elastic shear wave" on math sites and in literature. полубесконечный дефект = semi-infinite crack/imperfection And here are some examples of nearly "yours" sentence: Elastic wave diffraction by a semi-infinite crack in a transversely isotropic material, AN Norris and JD Achenbach, Quarterly J.

Diffraction of elastic shear waves by a semi-infinite defect

Explanation:
The second half poses problems.See ref for an example.

I see the defect here (idealized as one-way infinite) either as a half-line crack, or as a regular sequence of defects.

semi-infinite defect diffraction of an elastic shift wave

Explanation:
Other suhhestion are very non-profesional since
semi-infintei defect diffraction is the correct term describeing your process.
Of course you might place here

diffraction of an elastic wave of shift on a semi-infinite defect,

but, as far I know, the author have in mind namely
"Diffraction caused by a semi-infinite shift (the word translation does not
fit too well here) of an elastic wave". But your cannot write this in mathematical English since this will mean something like a general diffraction of .... an elastic wave (and now this wave is caused .... by semi=infinite shift)... I see thos is not too reasonable from math-al standpoint.

So, would you mind to spend your time to search of author's e-mail, please use other ay of consulting in fields close to mathematics
www.emis.de where you must choose famous Zentralblatt's referene index of articles related to the matter.

Some other suggestions mean
дифракция упругой волны сдвига на полубесконечнЫЙ дефект BUT your source is DIFFERENT !!!

Diffraction of elastic shear wave by a semi-infinite crack/imperfection

Explanation:
дифракция = diffraction

упругая волна сдвига = elastic shear wave
(СДВИГОВАЯ ВОЛНА, поперечная упругая волна, распространяющаяся в твердом теле и вызывающая деформацию сдвига, смещения частиц в которой перпендикулярны направлению ее распространения). I failed to find any "shift wave" or "wave of shift" in any available dictionary.
But there are many examples of "elastic shear wave" on math sites and in literature.

полубесконечный дефект = semi-infinite crack/imperfection

And here are some examples of nearly "yours" sentence:

Elastic wave diffraction by a semi-infinite crack in a transversely
isotropic material, AN Norris and JD Achenbach, Quarterly J. Mechanics and ...
cronos.rutgers.edu/~norris/publications/

... Achenbach b,l = d (2) p'+ ioq 3' (1985) studied the problem of elastic-wave diffraction by interface imperfections due to a periodical array of cracks. We have ...

to scattering of SH waves by surface irregularities," Bull. Seism. Soc ...
www.wspc.com.sg/profiles/anncat/anncat/jnlarticle/jcav8n1/S...

As you can see, preposition "by" is mostly used for "на". Therefore the whole sentence should be translated as "Diffraction of elastic shear wave by a semi-infinite crack/imperfection"

Examples of "elastic shear wave" usage:

Elastic shear wave modelling in
inhomogeneous anisotropic media by quasi-isotropic approximation .
