    Interaction of Short Pulses of Focused Ultrasound with Interfaces and Plane-Parallel Objects

    Short pulses of focused ultrasound are effective instrument for measuring local velocity values of bulk acoustic modes and for studying local elastic properties of solids (microacoustical technique). The probe...

    Measuring Sound Velocities and Anisotropy of Microstructural Units of Laminate Composite Materials by Microacoustical Technique

    The CFR composites are manufactured as laminate packages of ordered carbon fiber layers (prepreg plies) embedded into a polymer binder (epoxy, bismeleimide or other types of polymer resin). Elastic properties ...

    Application of Microacoustical Technique to Study Elastic Properties and Microstructure of New Generation of Bulk Metallic Glasses

    Elastic properties of bulk metallic glass (BMG) Pd39Ni10Cu10P21 have been studied basing on sonic velocity data analysis. Different states of the Pd39Ni 10Cu 1 oP21 system (glassy state, super-cooled liquid (SCL)...
