Interfacial Bond Properties between Normal Strength Concrete and Epoxy Resin Concrete
Advances in Materials Science and Engineering, 2021 It is necessary to pay attention to the bonding strength of the interface between precast normal strength concrete (NSC) and cast-in-place epoxy resin concrete (EMR) when using EMR as a repair or filling material or an overlay in bridges’ rehabilitation.

Discrete element model for high strain rate deformations of snow [PDF]
arXiv, 2020 In engineering applications snow often undergoes large and fast deformations. During these deformations the snow transforms from a sintered porous material into a granular material. In order to capture the fundamental mechanical behavior of this process a discrete element (DE) model is the physically most appropriate.

Mechanical Metastructures of Triple Periodic Carbon Clathrates [PDF]
arXiv, 2020 Clathrates are lightweight, cage-like, fully-sp3 three dimensional (3D) structures that are experimentally-available for several host elements of the IV group. However, carbon clathrates are as yet hypothetical structures. Herein, the mechanical properties of Type-I-C46 Type-II-C34 and Type-H-C34 carbon clathrates are explored by first-principles ...

Factors Affecting the Shear Bond Strength of Orthodontic Brackets - a Review of In Vitro Studies.
Acta medica, 2015 The adhesive material used to bond orthodontic brackets to teeth should neither fail during the treatment period, resulting in treatment delays, untoward expenses or patient inconvenience nor should it damage the enamel on debonding at the end of the ...
