Justification of fracture criteria for salt rocks
Fracture and Structural Integrity, 2022 The study of salt rocks deformation and fracture processes is an essential part of mining parameters justification for mineral salt deposits. The results of uniaxial compression tests on large salt rock specimens are presented as a loading curve and ...

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 ...

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.

Ductile Fracture Prediction in Hole Hemming of Aluminum and Magnesium Sheets
Metals, 2023 The present work proposes a suitable approach for predicting ductile fracture in a new joining process by plastic deformation called hole hemming. This process creates a combined form- and force-fit joint and enables the joining of lightweight materials ...

Evaluation of interfacial toughness function in mixed mode loading
Vietnam Journal of Mechanics, 2012 Interfacial strength is one of important factors to affect working stability of structures and devices. In order to avoid interfacial cracking, an improved method based on the conventional one is proposed to establish the interfacial toughness function (
