Integral Equations In Elasticity – Parton, Perlin

In this post, we will look at the book Integral Equations In Elasticity by V. Z. Parton, P. I. Perlin.

About the book

This book presents the fundamentals of the theory of regular and singular integral equations in the case of one and two variables. The general principles of the theory of approximate methods are considered as well as their application for the efficient solution of both regular and singular integral equations. The necessary information is given on the three-dimensional and two-dimensional equations of the theory of elasticity including the formulation of boundary value problems. The book contains the derivation and analysis of various integral equations of the plane problem for both fundamental boundary value problems and mixed problems, and also for bodies with cuts. In the three-dimensional case the construction and analysis of integral equations are carried out for the first and second fundamental problems.

Emphasis is placed on efficient methods for solving integral equations for the plane and three-dimensional problems of elasticity. Examples are given illustrating the advantages of a particular approach. The book is appended with an extensive list of references giving comprehensive information of the subject of investigation.

The emphasis on numerical methods for the solution of integral equations for elastostatic problems corresponds to the author’s conviction that this approach has considerable promise, particularly with the advent of the nearest-generation computers.

The scope of the book is limited to elastostatic problems though the extension of the methods described to dynamic problems apparently involves no fundamental difficulties.

The book was translated from the Russian by ???? and was published by Mir in 1982.

Many thanks to Akbar Azimi for the scans.

Plugging Materials and the Cementing of Wells – Bulatov

In this post, we will see the book Plugging Materials and the Cementing of Wells by A. Bulatov.

About the book:

This textbook, translated from the third Russian edition, is intended for students at technical schools specializing in the drilling of oil and gas wells. The book outlines the techniques of cementing oil and gas wells, based on current scientific developments and experience gained in applying advanced methods by the Soviet oil-industry specialists, and offers a description of cementing outfit, plugging cements, and chemicals used for their
treatment. It also surveys the properties of plugging mixtures (slurries) and cement stone under a variety of geological and technical conditions.

One of the merits of the text is that it describes the composition of plugging cements and techniques employed in their preparation, which is of great importance in training technical personnel at oil fields.

The book will be of particular value in countries where oil is being produced with the participation of the Soviet specialists and with use of the Soviet-made equipment.


The book was translated from the Russian by S. Kittell and was published by Mir in 1985 (Second Edition).

Many thanks to Akbar Azimi for the scans.

Problems On The Equations Of Mathematical Physics – Smirnov

In this post we will see the book Problems On The Equations Of Mathematical Physics by M. M. Smirnov.

About the book

The aim of the present collection of problems is to illustrate the theory of partial differential equations as it is given in various textbooks.
The problems of this collection are divided in three paragraphs. The first paragraph contains introductory excercizes on the reduction of partial differential equations to canonical form. The second paragraph deals mainly with problems, the general solution of which can be formed by means of the method of characteristics e.g. Cauchy’s (or also Goursat’s) and mixed problems.

In the third paragraph the most important method is presented, namely the separation of variables. This is done for mixed problems (for hyperbolic and parabolic equations) and for boundary value problems (elliptic equations).

The solutions of all excercizes are given. Most of the problems are accompanied by an explanation of the solution method used: so that this problem book can also be used for self study.

The book was published by Nordoff in 1967 and was translated from the Russian by W. I. M. Wils.
