Coupling of phase field and viscoplasticity for modelling cyclic softening and crack growth under fatigue
نویسندگان
چکیده
A coupled phase field-viscoplasticity approach was developed to model the deformation and crack growth in a nickel-based superalloy under fatigue. The has an advantage predicting cyclic softening behavior of alloy caused by fatigue damage, overcoming major limitation original viscoplasticity model. is also highly effective propagation varied dwell times at peak load, important for By incorporating stress state factor, further utilized investigate 3D cracks Both geometrical feature front overall rate are well captured, confirming predicative capability

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Fatigue crack growth characteristics of Fe and Ni under cyclic loading using a quasi-continuum method
A quasi-continuum (QC) method based on the embedded atom method (EAM) potential was employed to investigate the fatigue crack growth and expansion characteristics of single-crystal Fe and Ni under cyclic loading modes I and II. In particular, the crack growth and expansion characteristics of Fe and Ni under cyclic loading were evaluated in terms of atomic stress fields and force–distance curves...
متن کاملStrip yield modelling of fatigue crack under variable amplitude loading
The results from ‘strip yield’ approach of the FASTRAN type models of plasticity induced crack closure effects of fatigue cracks subjected to variable amplitude loadings are presented. The strip yield results are compared with authors’ finite element (FE) and experimental results. It has been observed that the strip yield model is seen to be fundamentally limited by choice of α (constraint fact...
متن کاملFatigue crack growth in ferroelectrics driven by cyclic electric loading
Fatigue crack growth has been observed recently in ferroelectrics under cyclic electric loading[ Does the crack grow by electric breakdown\ or by the stress _eld near the crack tip< The present paper provides a mechanistic explanation for the electric!_eld!induced fatigue crack growth[ The non!uniform electric _eld near an insulated crack tip might cause domain switching which in turn produces ...
