Abstract: The problem of acoustic monochromatic radiation by boundary with a traveling distribution of phases of normal vibrational velocities is considered. It is shown that when the spatial frequency of the traveling phase of normal velocities approaches the wave number in the medium, the energy transfer from boundary   into a “sliding” (with respect to the boundary)… Read More

Abstract: In fact, aggregates in concrete generally occupied a considerable proportion of volume (60%-75%); sand constitutes about 30% to 50% of aggregates volume. It is well known that the nature of aggregates plays an important role on quality and properties of concrete. This suggests that the behavior of concrete exposed to high temperature is strongly linked… Read More
