Mixed Mode Fracture of Concrete under Proportional and Nonproportional Loading
A novel testing procedure for mixed mode crack propagation in concrete is presented: four point bend of notched beams under the action of two independent force actuators. In contrast to classicalExpand

The cohesive zone model: advantages, limitations and challenges
Abstract This paper reviews the cohesive process zone model, a general model which can deal with the nonlinear zone ahead of the crack tip––due to plasticity or microcracking––present in manyExpand

A general bilinear fit for the softening curve of concrete
The softening function is the main input needed to model the fracture of concrete when using a cohesive crack approach. The simplest softening function that describes concrete behaviour reasonablyExpand

Measurement of the fracture energy using three-point bend tests: Part 3—influence of cutting theP-δ tail
Available measures of the fracture energyGF obtained with the procedure proposed by RILEM TC-50 provide values that appear to change with sample size, calling into question the possibility ofExpand

Measurement of the fracture energy using three-point bend tests: Part 2—Influence of bulk energy dissipation
Avialable measures of the fracture energy GF obtained with the procedure proposed by RILEM TC-50 provide values that appear to change with sample size, calling into question whether GF can beExpand

Stress Intensity factor, compliance and CMOD for a General Three-Point-Bend Beam
New simple and general expressions for the stress intensity factor, compliance and crack mouth opening displacement for three-point bend specimens are computed. Inverse functions giving the crackExpand

FRACTIONAL CALCULUS APPLIED TO MODEL ARTERIAL VISCOELASTICITY
Arterial viscoelasticity can be de- scribed using stress-relaxation experiments. To fit these curves, models with springs and dashpots, based on differential equations, were widely studied. However,Expand

Stretching of supercontracted fibers: a link between spinning and the variability of spider silk
SUMMARY The spinning of spider silk requires a combination of aqueous environment and stretching, and the aim of this work was to explore the role of stretching silk fibers in an aqueous environmentExpand

Self-tightening of spider silk fibers induced by moisture
Abstract Spider dragline silk has a unique combination of desirable mechanical properties—low density, high tensile strength and large elongation until breaking—that makes it attractive from anExpand
