Epoxy resin‐based sealers modified with clay nanoparticles: Evaluation of their physicochemical and mechanical properties

European Journal of Oral Sciences, EarlyView.
Abstract Epoxy resin‐based sealers are commonly used in endodontic treatment due to their superior physicochemical properties. Therefore, it is important to utilize these materials by enhancing their properties. Nonetheless, several of their properties remain suboptimal, including the relatively prolonged setting time, the moderate yet clinically ...

Computational Investigation on the Combined Effect of Applied Strain and Pore Configuration on Strain Concentrators in Additively Manufactured Metals

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...

Micromechanical Analysis of Lateral Pipe–Soil Interaction Instability on Sloping Sandy Seabeds

Journal of Marine Science and Engineering
The micromechanical mechanism of pipe instability under lateral force actions on sloping sandy seabeds is unclear. This study investigated the effects of slope angle and instability direction (upslope or downslope) on pipe–soil interaction instability ...

Mechanics of damping for fiber composite laminates including hygro-thermal effects [PDF]

An integrated mechanics theory was developed for the modeling of composite damping from the micromechanics to the laminate level. Simplified, design oriented equations based on hysteretic damping are presented for on-axis plies, off-axis plies, and ...

Transillumination‐Aided Infiltration of MIH‐Affected Molars: Evaluation of the Clinical Workflow

International Journal of Paediatric Dentistry, EarlyView.
ABSTRACT Background Enamel affected by molar incisor hypomineralisation (MIH) exhibits reduced mechanical properties due to its disorganised prismatic structure, lower mineral density and higher protein content. These alterations increase porosity and susceptibility to posteruptive enamel breakdown.

Self‐Adhesive Flowable Resin Composites—Are We Going Somewhere?

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To map laboratory/clinical evidence on self‐adhesive flowable resin composites (SAFRCs), tracing their chemical evolution, performance, and behavior, and to identify gaps that must be addressed to drive their optimization. Overview A comprehensive literature search was performed in PubMed/MEDLINE, Scopus, and LILACS without language ...

Modelling for the electrical conductivity of graphite-modified asphalt concrete based on micromechanics

Građevinar
This paper proposes a novel micromechanics theory to model the electrical conductivity of graphite-modified asphalt concrete. The constraint range of electrical conductivity was derived according to the Hashin–Shtrikman (H–S) method.
