A Macroscopic Strength Criterion for Isotropic Metals Based on the Concept of Fracture Plane
Metals, 2019 Although the linear Mohr−Coulomb criterion is frequently applied to predict the failure of brittle materials such as cast iron, it can be used for ductile metals too.

The Failure Analysis of Composite Bolted Joint Structure Based on a Nonlinear Model
Hangkong gongcheng jinzhan, 2019 Composite bolted joints have been widely used in aircraft structures. It is important to study their tensile failure. A three dimensional nonlinear model is established by combining the Hashin’s criterion, energy dissipation rate method, Puck’s criterion

Uncertainty assessment of onset sand prediction model for reservoir applications
Cogent Engineering, 2018 Modeling physical systems in engineering always comes with uncertainties in terms of the model’s input parameters. These uncertainties are also present in modeling the onset of sand production, even though considerable effort may be required in ...

Failure criteria for C/SiC composites under plane stress state
Theoretical and Applied Mechanics Letters, 2014 The applicability and limitation of several quadratic strength theories were investigated with respect to 2D-C/SiC and 2.5D-C/SiC composites. A kind of damage-based failure criterion, referred to as D-criterion, is proposed for nonlinear ceramic ...

Strain-based Applicability Evaluation of Girth Welds on High-grade Steel Pipeline
Shiyou jixie, 2022 Current pipeline design standards mostly follow the traditional stress-based design criteria.When the pipe yield and strain are strengthened,the stress-based design criteria are no longer applicable.In order to effectively evaluate the applicability of ...

Slope failure criterion for the strength reduction material point method
地质科技通报, 2022 It is necessary to select an instability criterion for the material point strength reduction method (SRMPM) to solve the slope safety factor (Fs), and there are some differences in the obtained Fs values with different instability criteria.

Numerical Investigation on the Dynamic Responses and Failure Criterion of RC Beam Under Impact
Frontiers in Materials, 2022 During the period of service, the infrastructure is subjected to various forms of impact. To investigate the impact responses of a reinforced concrete (RC) beam, a numerical model of the RC beam under impact was developed by the finite element package LS-

New Failure Criterion for Rock.
Shigen-to-Sozai, 1993 Newly proposed failure criterion for rock is expressed by eT=eTC, whereeT is tensile strain and eTC is critical tensile strain. Some experimental results which support the criterion are shown.
