Investigation of different discrete modeling strategies to mimic microstructural aspects that influence the fracture energy of refractory materials

Open Ceramics, 2022
The mismatch between the coefficient of thermal expansion of the constituents within refractory ceramics could advantageously be used to tune the fracturing behavior by inducing numerous microcracks within the microstructure.

The paradigm of the area law and the structure of transversal and longitudinal lightfront degrees of freedom [PDF]

, 2002
It is shown that an algebraically defined holographic projection of a QFT onto the lightfront changes the local quantum properties in a very drastic way.

Wedge splitting test for a steel–concrete interface

Engineering Fracture Mechanics, 2005
Abstract This paper presents a test method designated for the determination of the stress–crack opening relationship of a steel–concrete interface. The method is based on the well known wedge splitting test (WST), and it is illustrated how to obtain the stress–crack opening relationship through an inverse analysis.

Construction of two-dimensional quantum field models through Longo-Witten endomorphisms [PDF]

, 2014
We present a procedure to construct families of local, massive and interacting Haag-Kastler nets on the two-dimensional spacetime through an operator-algebraic method. An existence proof of local observable is given without relying on modular nuclearity.

Measurement of Birefringence of Low-Loss, High-Reflectance Coating of M-Axis Sapphire [PDF]

, 2001
The birefringence of a low-loss, high-reflectance coating applied to an 8-cm-diameter sapphire crystal grown in the m-axis direction has been mapped. By monitoring the transmission of a high-finesse Fabry-Perot cavity as a function of the polarization of

Experimental Study on the Influence of Humidity on Double-K Fracture Toughness and Fracture Energy of Concrete under Water Environment

Buildings, 2023
Saturated concrete is significantly different from dry concrete in fracture mechanical properties. Using the wedge-splitting tensile method to research the rule of change in moisture content, double-K fracture toughness and fracture energy of three ...

Retention of a Primordial Cold Classical Kuiper Belt in an Instability-Driven Model of Solar System Formation [PDF]

, 2011
The cold classical population of the Kuiper belt exhibits a wide variety of unique physical characteristics, which collectively suggest that its dynamical coherence has been maintained through out the solar system's lifetime.

Experimental Study on Fracture Properties of Hydraulic Concrete with Different Crack-Depth Ratios Based on Acoustic Emission and DIC Techniques

Advances in Materials Science and Engineering, 2022
In order to study the fracture behavior of hydraulic concrete, wedge splitting tests are performed on notched cubic concrete specimens with different crack-depth ratios (0.3, 0.4, and 0.5).
