Edited by . T. Cruz, F. Rizzo . — Per. with English. In. M. Weinschelbaum at ed. R. In. Goldstein . - M. : World, 1978. — 210 s. The book introduces the reader to the use of a new method of numerical solution of problems of mechanics - the so-called method of boundary integral equations. This method, which has received increasing attention in recent years, makes it possible to effectively solve complex problems arising in engineering practice with the help of computers. It makes it possible to reduce the dimension of tasks, which serves as its main advantage over other numerical methods. The use of the method is demonstrated on the solution of flat and spatial problems of hydrodynamics - the theory of elasticity, plasticity, fracture mechanics, rock mechanics, non-stationary theory of thermal conductivity .. The book is of interest to a wide range of applied mechanics and engineers, and will be useful to undergraduate and graduate students specializing in continuum mechanics and applied mathematics.
