Predicting crack propagation with peridynamics: a comparative study

Abstract: The fidelity of the peridynamic theory in predicting fracture is investigated through a comparative study. Peridynamic predictions for fracture propagation paths and speeds are compared against various experimental observations. Furthermore, these predictions are compared to the previous predictions from extended finite elements (XFEM) and the cohesive zone model (CZM). Three different fracture experiments are modeled using peridynamics: two experimental benchmark dynamic fracture problems and one experimental… Show more

“…Alternative approaches using discrete elements, which try and bypass this such as the Element Free Galerkin Method (EFG) or Peridynamics, Fig. 6(d), often struggle with application of boundary conditions meaning they require millions of elements to resolve discontinuities [7,22]. This therefore makes eXtended Finite Element Method (XFEM) a more sensible choice than other approaches by bypassing the need re-mesh.…”

“…They also observed the crack propagation process for a fast brittle crack contained a large diffuse zone of micro-cracks ahead of the tip. This process produced an oscillating macro-crack profile, slowing down the crack, leading in some cases to macro-crack branching [6,7].…”

“…Первый такой метод был предложен в работе [12] и применен к исследованию ветвления трещин. Дальнейшее развитие -это, как правило, объединение подхода работы [12] с тем или иным вариантом метода конечных элементов, а также использование различных кон-ституционных соотношений для сил сцепления (см., например, работы [11,[13][14][15][16]). …”
