TL;DR: In this paper, a comprehensive review on the application of proppants to maintain fracture permeability over the lifetime of a well based on published observations from experiments and modeling is provided, identifying the challenges and knowledge gaps that also provide future avenues of research and opportunities for collaborative technological development which requires an interdisciplinary approach of science, engineering in academia, government, and private sector.

TL;DR: In this article, a detailed three-dimensional finite element models of the pullout behaviour of strands in the keyway of precast concrete blocks and of the ductility behavior of floor joints subjected to uniform and line loads exerted from upper walls were developed.

TL;DR: In this paper, a plastic-capped decorative article and method of manufacture are described, which includes a plastic cap which is applied over a decorated embedment positioned on a layer of pressure sensitive adhesive and then cured.
Abstract: A plastic-capped decorative article and method of manufacture are provided. The article includes a plastic cap which is applied over a decorated embedment positioned on a layer of pressure sensitive adhesive and then cured. Optionally, the upper surface of the adhesive may be treated to render its substantially tack free and suitable for printing thereon prior to the application of the plastic cap.

TL;DR: In this paper, the European yield model (EYM) is used in many standards and accepted as a very accurate model for the calculation of the ductile failure strength or the load carrying capacity, but embedment strength values are not available for New Zealand Radiata pine or laminated veneer lumber.
Abstract: Connections with mechanical fasteners are important for all cases of timber structures. The failure of these connections may occur in either ductile or brittle manner. For the calculation of the ductile failure strength or the load carrying capacity, the European yield model (EYM) is used in many standards and accepted as a very accurate model. In the current New Zealand timber standard NZS 3603:1993 (Standards New Zealand, 1993) and the Australian one AS1720.1-1997 (Standards Australia, 1997), the design concept for bolted or dowelled connections is not based on the EYM, and depends only on the diameter, the timber thickness and the species group. The most important parameters for the EYM are the fastener yield moment and the timber embedment strength, but embedment strength values are not available for New Zealand Radiata pine or laminated veneer lumber (LVL). To obtain the missing information and to implement the EYM into the New Zealand and Australian standards, embedment tests parallel, perpendicular and under various load-to-grain angles with different dowel diameters in Radiata pine lumber and LVL were conducted and compiled to build a database of embedment strength values. This paper includes the latest results of the investigations with dowel diameters extended up to 30 mm. Furthermore, different international testing standards are compared and their evaluation methods are used. The test results are also compared with the corresponding results using the Eurocode 5 formulas, and show that adjusted formulas of the Eurocode 5 can be used to predict the load carrying capacity of bolted and dowelled connections in Radiata pine lumber and LVL. Design examples comparing the current methods from the New Zealand/Australian design standards and the proposed method adopted from the EYM of the European design standard are given as well.

TL;DR: In this article, a modified method based on the nominal stress concept is developed to evaluate fatigue lives of complex multi-fastener joints, informed by fatigue characteristics of joints with similar structural details.
