Kinetic relations and local energy balance for LEFM from a nonlocal peridynamic model

Journal: International Journal of Fracture

Abstract: A simple nonlocal field theory of peridynamic type is applied to model brittle fracture. The kinetic relation for the crack tip velocity given by Linear Elastic Fracture Mechanics (LEFM) is recovered directly from the nonlocal dynamics, this is seen both theoretically and in simulations. An explicit formula for the change of internal energy inside a neighborhood enclosing the crack tip is found for the nonlocal model and applied to LEFM.

An improved semi-analytical solution for stress at round-tip notches

Highlights

 

A semi-analytical model is developed for the notch tip maximum stress.

Application of the formula to U and blunt V-notches is demonstrated.

The results can be used to assess the brittle failure of notched components.

Fracture mechanics is one of the key research topics in our field (of mechanics) and has a rather rich history of innovation and applications. From earth-quakes to air-planes---the mechanics underpinning the phenomenon of materials falling apart has been essential in the development of technology.  Griffith’s work on fracture was published about a 100 years ago and is often widely regarded as the start of modern fracture mechanics.

PhD position in computational solid / fracture mechanics

Hello,

I have a PhD position available for a project titled "Asynchronous, Parallel-Adaptive Solution of Extreme Multiscale Problems in Seismology" funded by the U.S. National Science Foundation (NSF). The research involves:

a. Formulation of contact / fracture models (interfacial and/or bulk) for seismic applications, e.g. anisotropic, inhomogeneous rock under dynamic loads.

b. Adaptive spacetime time discontinuous Galerkin formulation for the solution of multiphysics PDEs relevant to this application.

c. High performance computing aspects of the method.

Eigenerosion for static and dynamic brittle fracture

In contrast to many numerical methods, the eigenerosion approach yields a convenient description of fracture handled in the postprocessing part of a Finite Element Analysis (FEA). Its fully energetic formulation avoids the introduction of extra degrees of freedom to model fracture propagation. Following previous works on eigenerosion, in this publication, a modified formulation of eigenfracture it is introduced, where it is distinguished between compression and tension loaded state.
