Moving mesh finite element simulation for phase-field modeling of brittle fracture and convergence of newton's iteration

, 2017
A moving mesh finite element method is studied for the numerical solution of a phase-field model for brittle fracture. The moving mesh partial differential equation approach is employed to dynamically track crack propagation. Meanwhile, the decomposition

Compression Stress Effect on Dislocations Movement and Crack propagation in Cubic Crystal [PDF]

, 2011
Fracture material is seriously problem in daily life, and it has connection with mechanical properties itself. The mechanical properties is belief depend on dislocation movement and crack propagation in the crystal.

Local and non-local normalised equivalent strain functionals for cyclic fatigue [PDF]

, 2004
The concept of Cyclic Normalised Equivalent Strain Functionals (CNESnFs) suitable for lowcyclic fatigue is developed in this paper. It reduces any fatigue strength and durability model to a unique form what facilitates the models comparison ...

Microstructural modelling of creep crack growth from a blunted crack [PDF]

, 1998
The effect of crack tip blunting on the initial stages of creep crack growth is investigated by means of a planar microstructural model in which grains are represented discretely. The actual linking-up process of discrete microcracks with the macroscopic

Effects of normal stress on shear properties and acoustic emission characteristics of bonded rock-concrete interfaces

Scientific Reports
Direct laboratory shear tests, accompanied by acoustic emission (AE) monitoring, were performed to examine the influence of normal stress (ranging from 4 to 16 MPa) on the shear behavior and acoustic emission characteristics of bonded granite-concrete ...
