Abstract

The propagation of plane waves in fibre-reinforced medium is discussed. The expressions of phase velocity of quasi-P (qP) and quasi-SV (qSV) waves propagating in plane symmetry are obtained in terms of propagation vector. We have established a relation from which displacement vector can be obtained in terms of propagation vector. The expressions for the reflection coefficients of qP and qSV waves are obtained. Numerical results of reflection coefficients are obtained and presented graphically. The partition of energy between qP and qSV waves reflected on a free boundary due to incident qP and qSV waves are also obtained and presented graphically.

The Reflection of Quasi Waves at Free Boundary of a Fibre-Reinforced Medium

New York, New York

The propagation of plane waves in fibre-reinforced medium is discussed. The expressions of phase velocity of quasi-P (qP) and quasi-SV (qSV) waves propagating in plane symmetry are obtained in terms of propagation vector. We have established a relation from which displacement vector can be obtained in terms of propagation vector. The expressions for the reflection coefficients of qP and qSV waves are obtained. Numerical results of reflection coefficients are obtained and presented graphically. The partition of energy between qP and qSV waves reflected on a free boundary due to incident qP and qSV waves are also obtained and presented graphically.
