Abstract
Ice, a quasi-brittle material with a complex crystal organization and found ubiquitously in nature, undergoes an impact fragmentation process that implies a rich physical mechanism, yet remains not thoroughly elucidated. We develop a highly robust and efficient meshless method for fluid–solid coupling, specifically designed to elucidate the mechanisms of crack propagation in S2 columnar ice subjected to high-speed water jet impacts. This method couples a low-dissipation Riemann smooth particle hydrodynamics approach with a non-ordinary state-based peridynamics model,1 enabling detailed exploration of fracture process. Our theoretical advancements enhance numerical stability at the fluid–solid interface and establish a precise ice constitutive model by capturing the unique hydrostatic pressure-dependent and rate-dependent plasticity within the peridynamics framework, effectively addressing challenges in both fluid and solid phases. Combined with high-velocity water jet impact experiments, this study successfully delineates the initiation and expansion of circumferential and radial cracks in ice plates. We demonstrate that these cracks, both circumferential and radial, originate from tensile failure induced by circular elastic–plastic stress waves initiated by point source shocks. Specifically, circumferential cracks emerge and propagate from the upper to the lower surface driven by radial tensile stress, while radial cracks, motivated by circumferential tensile stress, develop from the lower to the upper surface. This investigation not only provides a foundational understanding of ice impact fracturing but also establishes a versatile theoretical framework applicable to a wide range of quasi-brittle materials.
期刊介绍:
The aim of Journal of The Mechanics and Physics of Solids is to publish research of the highest quality and of lasting significance on the mechanics of solids. The scope is broad, from fundamental concepts in mechanics to the analysis of novel phenomena and applications. Solids are interpreted broadly to include both hard and soft materials as well as natural and synthetic structures. The approach can be theoretical, experimental or computational.This research activity sits within engineering science and the allied areas of applied mathematics, materials science, bio-mechanics, applied physics, and geophysics.
The Journal was founded in 1952 by Rodney Hill, who was its Editor-in-Chief until 1968. The topics of interest to the Journal evolve with developments in the subject but its basic ethos remains the same: to publish research of the highest quality relating to the mechanics of solids. Thus, emphasis is placed on the development of fundamental concepts of mechanics and novel applications of these concepts based on theoretical, experimental or computational approaches, drawing upon the various branches of engineering science and the allied areas within applied mathematics, materials science, structural engineering, applied physics, and geophysics.
The main purpose of the Journal is to foster scientific understanding of the processes of deformation and mechanical failure of all solid materials, both technological and natural, and the connections between these processes and their underlying physical mechanisms. In this sense, the content of the Journal should reflect the current state of the discipline in analysis, experimental observation, and numerical simulation. In the interest of achieving this goal, authors are encouraged to consider the significance of their contributions for the field of mechanics and the implications of their results, in addition to describing the details of their work.
