  1. Fracture Mechanics of Networks

    Hartquist, Chase M.Massachusetts Institute of Technology2025

    … physical model effectively reconciles strand mechanics and connectivity to predict fracture in diverse networks that constitute polymeric, architected, and biological materials. While traditional models predict the intrinsic fracture energy – the minimum energy to propagate a crack per unit …

    Hakimzadeh Khoee, SalmanUniversity of Illinois at Urbana-Champaign2015

    … research on interface bonding using fundamental fracture mechanics has been very limited and is still in its early stage. Furthermore, laboratory tests and analyses that capture a broad range of fracture behavior, such as opening and shearing, have yet to be developed. The main objectives of this …

  10. Three dimensional fracture mechanics computations using tetrahedral finite elements

    Rajaram, Harish, 1976-Massachusetts Institute of Technology1999

    … However, the extension of these techniques to fracture mechanics studies is hindered by the unavailability of a general method to obtain fracture mechanics singularity strength (J, K1, etc.) for tetrahedral meshes. An approach to obtain these parameters along a 3-D crack front using tetrahedral …
