Mechanical and fracture performance of fresh rubberized self-compacting concrete: A mini review [PDF]
Engineering and Technology JournalSustainable construction procedures use recyclable material; thus, the construction process and design choices are focused on planet health. SCC is a new generation of concrete that offers the achievement of high durability and flexibility in Rubberized ...

International Journal of Concrete Structures and Materials, 2020 As a type of cement-based composite reinforcement material, textile reinforced concrete (TRC) has the advantages of corrosion resistance, high bearing capacity and good crack limit performance. Its bonding performance with the existing concrete interface

A self-affine geometrical model of dynamic RT-PMMA fractures: implications for fracture energy measurements [PDF]
, 2015 Profilometric imaging of fracture surfaces of rubber toughened polymer has been performed at two different resolutions (a) at large scales [10 μ\upmu m–25 mm] using an opto-mechanical profilometer and (b) at small scales [0.195 μ\upmu m–0.48 mm] using an

Fracture analysis of debonding mechanism for FRP plates
, 2009 Inevitable flaws in the concrete-FRP interface govern plate debonding, and are not amenable to finite element analysis because the models require far more detail than will ever be available for the interface. This thesis describes a global-energy-balance

An adaptive finite element approximation of a variational model of brittle fracture [PDF]
, 2010 The energy of the Francfort–Marigo model of brittle fracture can be approximated, in the sense of Gamma-convergence, by the Ambrosio–Tortorelli functional.

A novel rate-dependent cohesive-zone model combining damage and visco-elasticity [PDF]
, 2013 This is the author’s post-print version of a work that was accepted for publication in Computers & Structures. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control ...

Buoyancy-driven crack propagation: the limit of large fracture toughness [PDF]
, 2007 We study steady vertical propagation of a crack filled with buoyant viscous fluid through an elastic solid with large effective fracture toughness. For a crack fed by a constant flux Q, a non-dimensional fracture toughness K=Kc/(3μQm3/2)1/4 describes the

Effectiveness of Hybrid Fibers on the Fracture and Shear Behavior of Prestressed Concrete Beams
Fibers, 2022 This study investigates the effectiveness of hybrid fibers (steel and macro-synthetic) on the shear behavior of prestressed concrete beams. The hybrid fiber combination was selected to avoid workability issues at high volume dosages and ensure effective ...

Molecular Oncology, EarlyView.Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.
