Mixed-mode dynamic crack growth behavior in a compositionally graded particle filled polymer is studied experimentally and computationally. Beams with single edge cracks initially aligned in the direction of the compositional gradient and subjected to one-point eccentric impact loading are examined. Optical interferometry along with high-speed photography is used to measure surface deformations...

This paper presents a practical approach for designing, erecting, and testing stone columns using the vibro-replacement method to improve soil bearing capacity under shallow foundations (isolated and raft foundations) for any typical building under small or medium loading conditions. Usually, the vibroreplacement method is used in soils with cohesive layers of mixed deposits, loose sand, or bot...

There is currently no accepted concept or approach for understanding and controlling discolouration risk associated with trunk mains. This paper assesses the applicability of cohesive layer theories to manage discolouration and a steady state empirical modelling tool that describes the process of particulate material accumulation. Results are presented from independent field experiments across ...

Background. Mineral trioxide aggregate (MTA) is a material that has recently gained popularity in the application of the vital pulp therapy. Along with the increasing use of MTA to this end, the permanent restoration material to be placed on MTA has become a significant issue. The aim of this in vitro study was to investigate the bond strength of the novel low-shrinkage silorane-based composite...

Abstract The present study is an attempt to investigate the relationship between cohesive readability of expository texts and reading comprehension in EFL students with different proficiency levels. One hundred students formed the participant of this study. They were undergraduate students majoring in English at University of Isfahan. To collect the relevant data, participants were divide...

Failure of dams due to overtopping is among the most frequent forms of embankment failures. Owing to massive and wide spread damage to structures and loss of lives associated with a dam failure, the subject has drawn the attention of scientists. The study also becomes essential for damage assessment and for development of early warning system of people downstream of the embankment. The rate of ...

Cohesive frames are linguistic elements that precede the grammatical subject in the main clause. This study investigated the frequencies and communicative purposes of cohesive frame types in results and discussion section of research articles from 4 disciplines. To run this study, 40 results and discussion sections of research articles were selected from 4 disciplines, namely Applied Linguistic...

This paper presents a new micromechanical model for a collection of cohesive zone models embedded between each mesh of a finite element-type discretization. It aims to forth fully extend the previous linear results of [1] to the calibration of damageable cohesive parameters (cohesive peak stress, critical opening displacement, cohesive energy, etc). The main idea of the approach consists in rep...

We have synthesized calcium phosphate-based, strontium (Sr) containing, porous ceramic granules for use as bone graft substitutes. The granules with a particle size between 1 and 2 mm and a (macro)-pore size around 200–500μm were mixed with a fibrin sealant to form a moldable composite material. The starting material with Sr contents between 0 and 100% Sr were precipitated from Ca/Sr solutions ...
