APPLICATION OF PLASTIC WAVE PROPAGATION TO SOIL COMPACTION BY IMPACT

Plastic Wave Propagation Model for Perforation of Metallic Plates by Blunt Projectiles

In this paper, a six-stage interactive model is presented for the perforation of metallic plates using blunt deformable projectiles when plastic wave propagation in both target and projectile is considered. In this analytical model, it is assumed that the projectile and target materials are rigid – plastic linear work hardened. The penetration of the projectile into the target is divided into s...

Wave propagation in elasto-plastic granular systems

Due to the nonlinear nature of the inter-particle contact, granular chains made of elastic spheres are known to transmit solitary waves under impulse loading. However, the localized contact between spherical granules leads to stress concentration, resulting in plastic behavior even for small forces. In this work, we investigate the effects of plasticity in wave propagation in elasto-plastic gra...

Wave propagation in the soil: theoretical background and application to traffic induced vibrations

This paper reviews the direct stiffness method for the calculation of harmonic and transient wave propagation in horizontally layered media. Developed in the early eighties by Kausel and Roësset, this method has become a standard tool for the computation of the Green’s functions in layered media. As it is based on a superposition of plane harmonic waves in the frequency-wavenumber domain, it is...

analysis of propagation of displacement wave in laminated plates subjected to impact

in this paper, the propagation of the waves in the laminated composite plates which is subjected to low velocity impact is investigated using the finite element method. a rigid metallic projectile with spherical nose is considered and the impact of this projectile with laminated composite is studied in this study. considering a finite element model the governing equations of the problem is disc...
