Abstract
The paper demonstrates the ability of beam lattices to reduce the amplitude of a wave generated by the external high-pressure impulse. Therefore such lattices are good candidates for the design of protective layers. The suggested lattice design is based on the comprehensive study of basic phenomena in a mass-spring chain with partly breakable springs. The protection is provided by a specific lattice layout architecture with sacrificial beam elements. The distributed damage caused by their failure weakens the lattice material. However, it remains intact, and the pressure applied to one boundary of the layer diminishes at the opposite boundary. The maximum amplitude is defined by the interaction between the waves of three different types: the leading wave propagating in the undamaged lattice, the phase transition wave following the leading wave, and the unloading wave propagating in the damaged lattice toward the phase transition front. Two phase transition zones may be generated, and their influence on the protection effect is examined.
期刊介绍：
This interdisciplinary journal provides a forum for presenting new ideas in continuum and quasi-continuum modeling of systems with a large number of degrees of freedom and sufficient complexity to require thermodynamic closure. Major emphasis is placed on papers attempting to bridge the gap between discrete and continuum approaches as well as micro- and macro-scales, by means of homogenization, statistical averaging and other mathematical tools aimed at the judicial elimination of small time and length scales. The journal is particularly interested in contributions focusing on a simultaneous description of complex systems at several disparate scales. Papers presenting and explaining new experimental findings are highly encouraged. The journal welcomes numerical studies aimed at understanding the physical nature of the phenomena.
Potential subjects range from boiling and turbulence to plasticity and earthquakes. Studies of fluids and solids with nonlinear and non-local interactions, multiple fields and multi-scale responses, nontrivial dissipative properties and complex dynamics are expected to have a strong presence in the pages of the journal. An incomplete list of featured topics includes: active solids and liquids, nano-scale effects and molecular structure of materials, singularities in fluid and solid mechanics, polymers, elastomers and liquid crystals, rheology, cavitation and fracture, hysteresis and friction, mechanics of solid and liquid phase transformations, composite, porous and granular media, scaling in statics and dynamics, large scale processes and geomechanics, stochastic aspects of mechanics. The journal would also like to attract papers addressing the very foundations of thermodynamics and kinetics of continuum processes. Of special interest are contributions to the emerging areas of biophysics and biomechanics of cells, bones and tissues leading to new continuum and thermodynamical models.
