Experimental and Numerical Research on Fracture Properties of Mass Concrete Under Quasi-Static and Dynamic Loading

Buildings
The dynamic fracture behavior of mass concrete is crucial to the dynamic analysis and safety evaluation of concrete dams subjected to strong earthquake shocks in the framework of fracture mechanics. In the presented research, cylindrical specimens with a

Validation of a finite element model for fracture mechanics specimens [PDF]

, 2012
Single parameter formulations have shown to be insufficient to describe constraint effects in fracture mechanics specimens. This has lead researchers to a two parameter approach like the J-Q theory. In order to investigate constraint effects, the authors

Shadowing effects in simulated Alcator C-Mod gas puff imaging data

Nuclear Materials and Energy, 2019
A synthetic gas puff imaging (GPI) diagnostic is applied to a gyrokinetic turbulence simulation of Alcator C-Mod with the objective of assessing the impact of turbulent plasma fluctuations on the GPI neutral density field.

Velocity profile shapes in Alcator C-Mod plasmas

Nuclear Fusion
Toroidal rotation velocity spatial profiles ( $r/a$ $ \lt $ 0.8) have been obtained from C-Mod over a wide range of operational conditions, including H-mode, I-mode, ICRF-heated L-mode and Ohmic L-mode (LOC and SOC), and in plasmas with ITBs, LH wave ...

Determination of fracture toughness in plain concrete specimens by R curve

Fracture and Structural Integrity, 2019
Experimental tests and computational algorithm are implemented to investigate crack growth phenomena in C0.7 concrete. Firstly, three point bending tests are carried out on normalized prismatic specimens notched laterally (SENB), then, computational ...

The effect of low-cycle fatigue on evolution of fracture mechanics parameters in residual stress field caused by cold hole expansion

Fracture and Structural Integrity, 2018
Localized displacement measurements based on electronic speckle-pattern interferometry are used to obtain crack mouth opening displacement (CMOD), stress intensity factor (SIF) and T-stress values during crack growth around cold-expanded holes.

INVESTIGATING THE CRACK PROPAGATION RESISTANCE OF NANO CONCRETE THROUGH FRACTURE MECHANICS

International Journal for Computational Civil and Structural Engineering
In the concrete treatments, small cracks are beginning developing inside. As a result of temperature and stress variations during extraction, the fragments will enlarge and unite to form some noticeable cracks.

Solving large scale linear programming [PDF]

, 1993
The interior point method (IPM) is now well established as a competitive technique for solving very large scale linear programming problems. The leading variant of the interior point method is the primal dual - predictor corrector algorithm due to ...

Elevated temperature crack growth [PDF]

The purpose of this program was to extend the work performed in the base program (CR 182247) into the regime of time-dependent crack growth under isothermal and thermal mechanical fatigue (TMF) loading, where creep deformation also influences the crack ...
