On the dynamic contact problem with two deformable stamps [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика
The problem of the time-harmonic behavior of two deformable semi-infinite stamps lying on a deformable base is considered. It is assumed that the stamps converge with parallel ends in such a way that they form a crack, defect, or tectonic fault in the ...

Diffraction by an acoustically penetrable or an electromagnetically dielectric half plane II [PDF]

, 1989
The present work gives a mathematical model for an acoustically penetrable or electromagnetically dielectric half plane. An approximate boundary condition is derived which depends on the thickness of, and the material constants which constitutes, the ...
