Fracture Criterion of Notched Plates of FRP

open access: yesJSME international journal. Ser. 1, Solid mechanics, strength of materials, 1988
The influence of notches on static tensile strength was studied for a composite material. Tension tests of notched plate for glass cloth/epoxy laminates have been carried out for a wide range of notch tip radii. All notched specimens failed in a brittle manner through the formation of small deformation near the notch tip.

Existence of solutions to a regularized model of dynamic fracture [PDF]

open access: yes, 2010
Existence and convergence results are proved for a regularized model of dynamic brittle fracture based on the Ambrosio–Tortorelli approximation. We show that the sequence of solutions to the time-discrete elastodynamics, proposed by Bourdin, Larsen ...

A mechanistic approach to the Kitagawa-Takahashi diagram using a multiaxial probabilistic framework [PDF]

open access: yes, 2013
The aim of this paper is to propose a flexible multiaxial modelling framework that is capable of combining two fatigue damage mechanisms so as to continuously describe the Kitagawa-Takahashi diagram.

Propagation process of hydraulic fracture crossing an orthogonal discontinuity

open access: yesRock and Soil Mechanics, 2023
Massive developed discontinuities are the salient geological features of unconventional oil and gas reservoirs, and the hydraulic fractures’ capabilities of crossing the discontinuities concern the stimulation effects of hydraulic fracturing.
