“…Linear elastic waves are widely used for the non-destructive analysis of internal structure and integrity of constructional elements [37]. Nonlinear elastic waves can be applied for the investigation of the nonlinearly elastic and viscoelastic properties of materials [38][39][40].…”

In this paper we compare two implementations of the holographic technique for recording long, nonlinear, elastic waves of low amplitude in solid polymer waveguides: classical holographic interferometry and digital holography. Both implementations are realized in transmission configuration, with recording in the off-axis schematic. The advantages and disadvantages of these implementations are discussed as applied to the investigation of the evolution of shock waves and strain solitons in transparent solid waveguides.

“…Other approaches developed to assess nonlinear elastic properties of materials utilize dynamic acousto-elasticity [12,13], second harmonic generation [14], Brillouin scattering [15], coda wave interferometry [16], strain solitary [17], Lamb [18] and Rayleigh [19] waves. However, no standard measurement procedure has been approved by now.…”

In this paper we apply the methodology based on the analysis of changes in acoustic wave velocities under static stress for measurements of the third-order elastic moduli in three polystyrene-based nanocomposites with different fillers: SiO 2 particles, halloysite natural tubules, and carbon black particles. The samples were fabricated by the same technology and our data provide information on relative changes of nonlinear properties of the composites caused by addition of the fillers. The data obtained for composites are compared with that for commercial grade polystyrene. The substantial variations of the nonlinear elastic moduli for composites with different types of fillers are demonstrated and analyzed. The results are in a qualitative agreement with theoretical predictions.

“…These methods are based on the analysis of nonlinear interaction of two strain waves [4], on measurements of elastic properties of a sample under shock wave loading [5] or on investigations of sound velocity variations as function of applied static or dynamic pressure [6]. Another approach suggests generation of a bulk nonlinear strain wave in three waveguides (rod, plate and shell) made of the same material and measurements of main parameters of the wave by means of digital holography [7][8][9][10]. While the first three approaches rely on traditional methods of investigation of nonlinear elastic properties of materials, and often utilize piezoelectric transducers for generation and detection of acoustic waves, the last method utilizes different techniques for both generation and detection of nonlinear strain waves.…”

“…As we have shown earlier, such waves are sensitive to variations of the elastic characteristics of the material, primarily, of the third-order elastic moduli, which describe the nonlinear properties of the material. As shown in [8,9] a set of soliton parameters obtained in three different waveguides (rod, plate and shell) made of the same material can provide data sufficient to determine these moduli.…”

The development and fabrication of novel composite materials requires accurate investigation of their mechanical properties. Although various approaches are well-established for investigation of linear elastic properties, there are only few methods that can be applied for study of nonlinear ones. In this report we describe and compare the performance of two different experimental approaches aimed for investigation of nonlinear elastic properties of glassy polymers and polymer-based composites.
