A Stress Tensor-based Failure Criterion for Ordinary State-based Peridynamic Models [PDF]
Journal of Applied and Computational Mechanics, 2022 Peridynamics is a recent nonlocal theory of continuum mechanics that is suitable to describe fracture problems in solid mechanics. In this paper, a new failure criterion based on the stress field is developed by adopting the damage correspondence model ...

Critical applied stresses for a crack initiation from a sharp V-notch [PDF]
Fracture and Structural Integrity, 2014 The aim of the paper is to estimate a value of the critical applied stress for a crack initiation from a sharp V-notch tip. The classical approach of the linear elastic fracture mechanics (LELM) was generalized, because the stress singularity exponent ...

Prediction and investigation of fracture initiation in warm forging of martensitic stainless steel with aid of fem simulation [PDF]
Computer Methods in Materials Science, 2015 Warm forging brings together advantages of hot (e.g. forging load reduction) and cold (e.g. no scale) metal forming operations. However, due to decreasing the process temperature, the risk of fracture occurrence increases.

Mode II brittle fracture: recent developments [PDF]
Fracture and Structural Integrity, 2017 Fracture behaviour of V-notched specimens is assessed using two energy based criteria namely the averaged strain energy density (SED) and Finite Fracture Mechanics (FFM). Two different formulations of FFM criterion are considered for fracture analysis. A

A new mixed-mode fracture criterion for large-scale lattice models [PDF]
Geoscientific Model Development, 2014 Reasonable fracture criteria are crucial for the modeling of dynamic failure in computational lattice models. Successful criteria exist for experiments on the micro- and on the mesoscale, which are based on the stress that a bond experiences.

Wheeled Vehicle Brake Drum Computation by Fracture Toughness Criteria [PDF]
Journal of Mechanical Engineering, 2020 To ensure vehicle safety at the design stage, of primary importance is the development of a mathematical model, within whose framework it is possible to effectively predict crack initiation in the break drum of a braking wheeled vehicle.
