Experimental study of elasto-plastic wave propagation in one-dimensional and two-dimensional disk arrays
… 30 kN respectively, cause the arrays to deform plastically at the contact points between disks where stress concentrations exist. This allows for elasto-plastic wave propagation to be studied in ordered 1D and 2D elasto-plastic arrays. Additionally, the loading pulse durations from the two …

Nonlinear Dynamics in Metamaterials under Elastic and Plastic Excitation and Spectral Submanifold Parameterization
… in many contexts, two of which, elastic-plastic wave propagation in metamaterials and nonlinear normal modes, are examined here. The first topic examined herein addresses the cross-section of plastic wave propagation and elastic metamaterials. Elastic metamaterials, media geometrically …

Wave management in 1D and 2D granular systems: designs for stress wave mitigation and control
Controlling stress waves during impact beyond merely dissipating their energy through material fracture, fragmentation, yielding etc., has been a significant focus of research in recent years. Materials exhibiting stress wave control characteristics would enable novel applications, such as for …

A finite strain theory of elastoplasticity and its application to wave propagation
A constitutive theory of finite strain plasticity is developed by using the methods of convex analysis. The theory abstracts and extends the classical assumptions of a convex region of admissible stresses, and the normality law. The overall effects of plastic behaviour are contained in the theory …

Quantifying Plasticity and Temperature in High Velocity Microparticle Impacts
… /s can be achieved while maintaining a subsonic plastic wave, preventing formation of strong shockwaves and hydrodynamic behavior. The LIPIT has been effectively applied to study phenomena in mechanical behavior, cold spray, and astronomical impacts, all of which will be further investigated in …

Experimental study of the development of plastic solitary waves in one-dimensional granular media
… and are of interest because of their unique wave propagation characteristics, as seen in earlier efforts. Loading magnitudes spanning from 9 kN to 40 kN – considerably higher than most previous works on these systems which have been conducted in the elastic regime – cause the granular chains …
