Automatic LEFM crack propagation method based on local Lepp–Delaunay mesh refinement
(ELSEVIER, 2010)
A numerical method for 2D LEFM crack propagation simulation is presented. This uses a Lepp–Delaunay
based mesh refinement algorithm for triangular meshes which allows both the generation of the initial
mesh and the local ...
3D concurrent multiscale model for crack propagation in concrete
(2020-04-01)
A new approach for concurrent multiscale modeling of three-dimensional crack propagation in concrete is proposed. A macroscopic model with homogenized elastic parameters is adopted in the regions where the material behaves ...
Experimental and numerical analysis of short fatigue cracks in Lean Duplex Stainless Steels
(Elsevier, 2014-06)
Transmission (TEM) and scanning electron microscopy (SEM) in combination with automated electron back-scattered diffraction (EBSD) techniques is used to study the surface damage as well as the initiation and propagation ...
Cyclic deformation mechanisms and microcracks behavior in high-strength bainitic steel
(Elsevier Science Sa, 2017-01)
The purpose of this investigation is to analyze the mechanisms of cyclic deformation and the initiation and propagation of microcracks during low cycle fatigue in the bainitic steel 16CrMnV7-7. The slip systems and their ...
Damage evolution during tensile test of austempered ductile iron partially austenized
(Wiley, 2020-02)
The goal of this work is to analyze the damage evolution at microstructural scale of an austempered ductile iron partially austenized during tensile loading. The analysis is carried out by means of step-by-step tensile ...
Modeling of crack propagation in a premolar tooth using finite elementmethod
(Universidade Federal de Minas GeraisUFMG, 2017-10-16)
e term cracked tooth syndrome refers to an incomplete fracture of a vital posterior tooth that involves the dentine and occasionally extends into the pulp. To better understand the characteristics of the cracked tooth ...
Initiation and growth of short cracks during cycling in an aged superduplex stainless steel
(Trans Tech Publications, 2011-08)
The kinetics of short crack growth during cycling has been studied in a superduplex stainless steel in aged condition. After few cycles, slip lines appear distributed in both phases but the preferred phase for microcrack ...
