Determining Crack Kinematics from Imaged Crack Patterns

open access: yesSSRN Electronic Journal, 2021
Determining the relationship between the cause of damage and the subsequent structural behavior of infrastructure systems requires an accurate characterization of the propagation of cracks, which represents the evolution of the damage state. When no information about the cause of damage is available, kinematic approaches can be used to describe the ...

Multi-cracks Modeling in Reflective Cracking [PDF]

open access: yes, 2012
Reflective cracking is a major concern for engineers facing the problem of road maintenance and rehabilitation. The problem appears due to the presence of cracks in the old pavement layers that propagate into the pavement overlay layer when traffic load passes over the cracks and due to the temperature variation. The stress concentration in the overlay
