IN THE WORK WITH SUBJECT "WAVE PROPAGATION OF ELASTIC WAVES IN COMPOSITE MATERIALS" HAVE BEEN DEVELOPED THE LOW-FREQUENCY SCATTERING THEORY OF ELASTIC WAVES BY A PENETRABLE SCATTERER WITH A PENETRABLE CORE. ANALYTICAL EXPANTIONS FOR THE SCATTERING AMPLITUDES AND FOR THE SCATTERING CROSS-SECTION HAVE ALSO BEEN DERIVED. USING THE SCATTERING CROSS-SECTION THE DYNAMIC MODULI OF COMPOSITE MATERIALS WITH RIGID SPHERICAL, ELLIPSOIDAL AND SPHEROIDAL INCLUSIONS HAVE BEEN COMPUTED. PARAMETER STUDIES FOR DESIGN PURPOSES ARE GIVEN.ΣΤΗΝ ΕΡΓΑΣΙΑ ΜΕ ΘΕΜΑ "ΔΙΑΔΟΣΗ ΤΑΣΙΚΩΝ ΚΥΜΑΤΩΝ ΣΕ ΣΥΝΘΕΤΑ ΥΛΙΚΑ ΚΑΙ ΠΡΟΣΔΙΟΡΙΣΜΟΣ ΤΩΝ ΔΥΝΑΜΙΚΩΝ ΤΟΥΣ ΙΔΙΟΤΗΤΩΝ" ΕΧΕΙ ΑΝΑΠΤΥΧΘΕΙ Η ΒΑΣΙΚΗ ΘΕΩΡΙΑ ΣΚΕΔΑΣΗΣ ΕΛΑΣΤΙΚΩΝ ΚΥΜΑΤΩΝ ΑΠΟ ΔΙΑΠΕΡΑΤΟΥΣ ΣΚΕΔΑΣΤΕΣ ΜΕ ΔΙΑΠΕΡΑΤΟΥΣ ΠΥΡΗΝΕΣ.
