Kinking of a Crack Out of an Interface [PDF]
Journal of Applied Mechanics, 1989 Kinking of a plane strain crack out of the interface between two dissimilar isotropic elastic solids is analyzed. The focus is on the initiation of kinking and thus the segment of the crack leaving the interface is imagined to be short compared to the segment in the interface.

Kinking conditions for running cracks [PDF]
Le Journal de Physique IV, 1994 The problem of the abrupt change of the direction of a crack, propagating with high velocity, is studied in the present work. The study is based on a unified approach of the directional instability phenomena, which accompany running cracks. According to this approach, the running tip is simulated by a prebranched configuration, consisted of two ...

Crack kinking at the tip of a mode I crack in an orthotropic solid [PDF]
International Journal of Fracture, 2017 The competition between crack penetration and crack kinking is addressed for a mode I macroscopic crack in an orthotropic elastic solid. Cohesive zones of finite peak strength and finite toughness are placed directly ahead of and orthogonal to the plane of the parent crack.

A Crack Kinked at the Interface of Bonded Anisotropic Elastic Media under Longitudinal Shear Stresses [PDF]
The stress intensity factors at the tips of a crack kinked at the interface of bonded anisotropic elastic media are analyzed. By using a singular point method, the problem is reduced to solving a system of singular integral equations with generalized ...

Mechanical Caging of Nucleic Acids Enabled by Light‐Activated Synthetic Molecular Motors
Angewandte Chemie, EarlyView.A synthetic light‐driven molecular motor imposes mechanical constraints on nucleic acids, enabling “mechanical caging” as a new mode to regulate DNA structure and function through mechanical input rather than chemical masking. ABSTRACT Control over nucleic acid activity is central to biotechnology and therapeutic development.
