[HTML][HTML] On stress singularity near the tip of a crack with surface stresses

N Gorbushin, VA Eremeyev, G Mishuris - International Journal of …, 2020 - Elsevier
In the framework of the simplified linear Gurtin–Murdoch surface elasticity we discuss a
singularity of stresses and displacements in the vicinity of a mode III crack. We show that …

A phase field fracture model for ultra-thin micro-/nano-films with surface effects

P Li, W Li, Y Tan, H Fan, Q Wang - International Journal of Engineering …, 2024 - Elsevier
Surface effects usually remarkably affect the mechanical response of ultra-thin micro-/nano-
structures. However, the mechanisms of surface effects on the fracture characteristics of ultra …

Analysis of plane-strain crack problems (mode-I & mode-II) in the presence of surface elasticity

CI Kim, P Schiavone, CQ Ru - Journal of Elasticity, 2011 - Springer
We consider plane deformations of a linearly elastic solid in the case where either a mode-I
or mode-II crack is present but, perhaps more significantly, when surface effects are included …

A clarification of the role of crack-tip conditions in linear elasticity with surface effects

CI Kim, CQ Ru, P Schiavone - Mathematics and Mechanics …, 2013 - journals.sagepub.com
We examine the role of crack-tip conditions in the reduction of stress at a crack tip in a theory
of linear elasticity with surface effects. The maximum number of allowable end conditions for …

Energy release rate, the crack closure integral and admissible singular fields in fracture mechanics

A Piccolroaz, D Peck, M Wrobel, G Mishuris - International Journal of …, 2021 - Elsevier
One of the assumptions of Linear Elastic Fracture Mechanics is that the crack faces are
traction-free or, at most, loaded by bounded tractions. The standard Irwin's crack closure …

Existence of solutions for the anti-plane stress for a new class of “strain-limiting” elastic bodies
