Review of time-dependent fracture model of concrete

矿业科学学报, 2021
The integrity of concrete structures under strong earthquakes and the stability of concrete structures with cracks are concerns of national security strategies.These two issues are closely related to the time-dependent fracture behavior of concrete.The ...

Fracture toughness and crack-resistance curve behavior in metallic glass-matrix composites [PDF]

, 2009
Nonlinear-elastic fracture mechanics methods are used to assess the fracture toughness of bulk metallic glass (BMG) composites; results are compared with similar measurements for other monolithic and composite BMG alloys.

Design and Application of a Miniature Pneumatic Bellows Loading Device for In-Situ Tensile Testing inside the Scanning Electron Microscope

Metals
A miniature pneumatic bellows device was designed for in-situ testing inside the scanning electron microscope. The device uses a pneumatic actuator to load the specimen and displacement is directly monitored with a linear variable differential ...

The Archimedes’ Constant, π Seen by Mechanical Engineers

Mathematical and Computational Applications, 2019
Probabilistic engineering mechanics is used to relate the value of π with one of the main parameters in fracture mechanics. It proposes an engineering method to obtain the value of it from engineering data without involving any geometrical ...

Size Effect in Fracture: Roughening of Crack Surfaces and Asymptotic Analysis

, 2002
Recently the scaling laws describing the roughness development of fracture surfaces was proposed to be related to the macroscopic elastic energy released during crack propagation [Mor00].

Comparison of the constraint parameters in elastic-plastic fracture mechanics Focused on Crack Tip Fields

Fracture and Structural Integrity, 2019
To describe the effect of crack-tip constraint on the stress field for finite cracked bodies, the following most widely used constraint parameters can be employed in elastic-plastic fracture mechanics, namely, local triaxiality parameter, constraint ...

Modified Fracture Mechanics Approach for Hydraulic Fracturing Stress Measurements

Geofluids, 2020
Hydraulic fracturing (HF) test has been widely used to determine in situ stress. The use of a conventional continuum method for this purpose has raised considerable controversies concerning field tests, particularly in the determination of the maximum ...

Cracked finite elements proposed for NASTRAN [PDF]

, 1973
The recent introduction of special crack-tip singularity elements, usually referred to as cracked elements, has brought the power and flexibility of the finite-element method to bear much more effectively on fracture mechanics problems.
