Transient damage spreading and anomalous scaling in mortar crack surfaces [PDF]

open access: yes, 2008
The scaling properties of a post-mortem mortar crack surface are investigated. The root mean square of the height fluctuations is found to obey anomalous scaling properties, but with three exponents, two of them characterizing the local roughness (zeta ...

Numerical simulation of grain-size effects on creep crack growth by means of grain elements [PDF]

open access: yes, 1998
The effect of grain size on creep crack growth is investigated by means of a numerical technique in which the actual crack growth process is simulated in a discrete manner by grain elements and grain boundary elements.

Mechanical properties and nugget evolution in resistance spot welding of Zn–Al–Mg galvanized DC51D steel

open access: yesHigh Temperature Materials and Processes, 2023
Zn–Al–Mg coating galvanized steel in resistance spot welded (RSW) in different configurations of DC51D was investigated to illustrate the nugget evolution process and mechanical properties of the joints.

Mathematical Modeling of Hydraulic Fracture Formation and Cleaning Processes

open access: yesEnergies, 2022
The effectiveness of the hydraulic fracturing procedure is crucially dependent on the stage of fracture planning and design. Forecasting fracture behavior in rock formations characterized by non-uniform toughness is a serious challenge.

Cohesive Dynamics and Brittle Fracture

open access: yes, 2015
We formulate a nonlocal cohesive model for calculating the deformation state inside a cracking body. In this model a more complete set of physical properties including elastic and softening behavior are assigned to each point in the medium.

Statistical extraction of process zones and representative subspaces in fracture of random composite [PDF]

open access: yes, 2012
We propose to identify process zones in heterogeneous materials by tailored statistical tools. The process zone is redefined as the part of the structure where the random process cannot be correctly approximated in a low-dimensional deterministic space ...

Evaluation on water bursting risk of working faces near collapse column during the mining process [PDF]

open access: yesE3S Web of Conferences, 2020
Collapse column water bursting occurs from time to time in the coal mining process of North China Type Coalfield in China, which causes great economic loss and personal injury. Therefore, great attention must be paid to the harm of collapse column.

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...
