Spherical wave diffraction by a rational wedge [PDF]

open access: yes, 1986
In this paper we derive a new expression for the point source Green's function for the reduced wave equation, valid in an angular sector, whoseangle is equal to a rational multiple of . This Green's function is used to find new expressions for the field

Fracture Behaviour of Concrete with Reactive Magnesium Oxide as Alternative Binder

open access: yesApplied Sciences, 2021
This research evaluates the fracture behavior of concrete with reactive magnesium oxide (MgO). Replacing cement with MgO is an attractive option for the concrete industry, mainly due to sustainability benefits and reduction of shrinkage.

Determining fracture energy parameters of concrete from the modified compact tension test [PDF]

open access: yesFracture and Structural Integrity, 2014
The modified compact tension (MCT) test, though not yet recognized as a valid test for determining fracture energy of concrete, is believed to represent a plausible and suitable alternative versus other well established procedures, such as the wedge ...

Investigation of the influence of impurities typical in secondary raw materials on the behavior of high alumina castables – Part 1: Design of the castables, setting properties and high temperature fracture behavior

open access: yesOpen Ceramics, 2023
The research was carried out using a primary high alumina raw material that was selectively spiked with typical elements found in secondary raw materials. These artificially spiked raw materials were processed into cement-free high alumina monolithics by

Non-uniqueness of fracture parameter choice in simulations of concrete cracking at mesoscale level

open access: yesArchives of Mechanics, 2023
In the paper a non-uniqueness of fracture parameter choice in simulations of cracking process in plain concrete specimens at mesoscale level under monotonic static loading is analysed.

A projection-based approach to extend digital volume correlation for 4D spacetime measurements

open access: yesComptes Rendus. Mécanique, 2023
In-situ (tomography) experiments are generally based on scans reconstructed from a large number of projections acquired under constant deformation of samples. Standard digital volume correlation (DVC) methods are based on a limited number of scans due to

Experimental studies and performance analysis of wedge splitting for concrete specimens with cavity defects

open access: yesShuili Shuiyun Gongcheng Xuebao, 2017
In order to investigate the defects such as the cavity influences on the wedge splitting performance of the concrete, the cavity is made equal to a loss of the height of the longitudinal section and the calculation formulas for the wedge splitting ...

Complex anisotropy beneath the Peruvian flat slab from frequency-dependent, multiple-phase shear wave splitting analysis [PDF]

open access: yes, 2013
Flat or shallow subduction is a relatively widespread global occurrence, but the dynamics remain poorly understood. In particular, the interaction between flat slabs and the surrounding mantle flow has yet to be studied in detail.

Influence of the Amount of Steel Fibers on Fracture Energy and Drying Shrinkage of HPFRCC

open access: yesAdvances in Materials Science and Engineering, 2020
The fracture energy of the high-performance fiber-reinforced cement-based composite (HPFRCC) can be modified within wide limits by the variation of the amount of steel fibers added to the fresh mix.
