Effect of Using Anti-Stripping on Fracture Behavior of Asphalt Mixtures Using Linear Elastic Fracture Mechanic (LEFM) Technic

Journal of Research in Science, Engineering and Technology, 2020
Today, cracking asphalt pavement in low temperature is one of the obstacles for protecting pavement in the cold climates. One of important factors in extending of these types of cracking is cooling and heating temperature cycles according to the changes in seasons. Therefore, this research examines these types of asphalt cracking by considering asphalt

A non-local continuum poro-damage mechanics model for hydrofracturing of surface crevasses in grounded glaciers

Journal of Glaciology, 2020
Hydrofracturing can enhance the depth to which crevasses propagate and, in some cases, allow full depth crevasse penetration and iceberg detachment.

BEM/OQM Formulation to Simulate Crack Problems

Trends in Computational and Applied Mathematics, 2008
Over the last few years the Boundary Element Method (BEM) has been successfully applied to linear elastic fracture mechanics problems (LEFM), involving static and dynamic cases. An approach to solve LEFM problems is presented in this work.

Models of buoyancy-driven dykes using continuum plasticity or fracture mechanics: a comparison [PDF]

Geoscientific Model Development
Magmatic dykes play an important role in the thermomechanics of tectonic rifting of the lithosphere. Our understanding of this role is limited by the lack of models that consistently capture the interaction between magmatism, including dyking, and ...

Residual strength evaluation by DBEM for a cracked lap joint [PDF]

Fracture and Structural Integrity, 2016
The present work summarizes a numerical procedure aimed at the evaluation of the residual strength of a cracked lap joint, based on the competing failure mechanisms regulated by the R-curve analysis and plastic collapse.

Analysis Fracture Behaviour of Asphalt Mixtures in Freezing and Thawing Cycles Conditions Using Linear Elastic Fracture Mechanic (LEFM) Technic

Journal of Research in Science, Engineering and Technology, 2019
Considering the military implementation prohibitions and highly developed technologies of composite materials , this project studies about increasing the power of martial and fire in Gyroplanes and light Helicopters by design, optimization and manufacturing of composite launchers instead of isotropic types. Using composite type launchers have advantage

Modeling Approach for Predicting the Rate of Frequency Change of Notched Beam Exposed to Gaussian Random Excitation

Shock and Vibration, 2014
During fatigue damage accumulation, cracks propagate through the material leading to catastrophic failure. As the cracks propagate, the natural frequency lowers, leading to a changing stress state.

A Numerical Study into the Effect of Machining on the Interaction between Surface Roughness and Surface Breaking Defects on the Durability of WAAM Ti-6Al-4V Parts

Metals, 2022
The airworthiness certification of military aircraft requires a durability analysis be performed using linear elastic fracture mechanics (LEFM). Furthermore, such analyses need to use a valid small crack growth equation.
