The 1/r singularity in weakly nonlinear fracture mechanics
, 2009 Material failure by crack propagation essentially involves a concentration of large displacement-gradients near a crack's tip, even at scales where no irreversible deformation and energy dissipation occurs. This physical situation provides the motivation

Nonadiabatic Study of Dynamic Electronic Effects during Brittle Fracture of Silicon [PDF]
, 2012 It has long been observed that brittle fracture of materials can lead to emission of high energy electrons and UV photons, but an atomistic description of the origin of such processes has lacked.

Fracture Mechanics of Plate Debonding [PDF]
Journal of Composites for Construction, 2008 This paper presents a fracture mechanics model to determine the load at which FRP plates will debond from reinforced concrete beams. This will obviate the need for finite-element analyses to be used in situations where there is an infinite stress concentration and where the exact details of the interface geometry and properties are unknowable.

Advanced Engineering Materials, EarlyView.This study investigates the mechanical properties of Carbon/Aramid intraply hybrid fiber‐reinforced Elium composites under 6 months of water aging. After aging, flexural strength decreases by 25.89%, tensile strength by 4.40%, and fracture toughness by 21.56%.

Toughness of carbon nanotubes conforms to classic fracture mechanics
Science Advances, 2016 The classic theory of fracture mechanics is found to be valid at the scale of single-walled carbon nanotubes. Defects in crystalline structure are commonly believed to degrade the ideal strength of carbon nanotubes.

Advanced Engineering Materials, EarlyView.The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of
