In recent years, acoustic microscopy has been found to be very useful for characterizing engineering as well as biological materials. With the present state of knowledge on acoustic microscopy, one can obtain the surface wave velocity of a homogeneous specimen or coating thickne…

A numerical method is developed to determine the dynamic behavior of delamination and transverse cracks in multilayered plates. The plate is subjected to a time dependent antiplane shear stress field which is acting on the plate surfaces. The interaction of waves diffracted at t…

Light scattering studies of the melting transition in phenyl salicylic acid commonly known as salol have been performed. Using a 5145(ANGSTROM) argon ion laser, both Brillouin and Raman scattering experiments on salol were performed very close to the melting point and down to ro…
