TL;DR: In this paper, the porosity analysis of Stabilized earth blocks reinforced with plant fibres of the date palm (PFDP) is presented. But the main objective of this study is the investigation of porosity phenomenon using several methods as well as the total porosity estimation, the total volume porosity in water and Open porosity methods, where the mechanical resistance is also considered.
Abstract: This work is an experimental study to analyze the physical behavior of Stabilized Earth Block (SEB) and reinforced with Plant Fibers of the Date Palm (PFDP). This is part of the valorization of local building materials (earth, fiber) and contributes to reduce the price of housing. Initially, physical tests (Density, Total Water Absorption, and Capillary Absorption) were carried out in preparation for the porosity study. However, the main objective of this study is the investigation of porosity phenomenon using several methods as well as the total porosity estimation, the total volume porosity in water and Open porosity methods, where the mechanical resistance is also considered. In order to improve the stabilized earth block porosity analyses, various dosages are proposed for cement, lime and fiber. Thus (0%, 5%, 10%) of cement, (0%, 5%, 10%) of lime and the combination (5% cement + 5% lime) with (0%, 0.25%, and 0.5%) of fibers for each composition. The experimental results showed that the addition of fibers increases the porosity of the stabilized earth block proportionally and an increasing quantity of the stabilizer reduces the porosity of the SEB, cement is also more effective at closing pores than lime. Moreover, the compositions 10% cement and the mixture of 5% cement + 5% lime with 0% fiber showed a good results of porosity, for this reason they can be used as a durable building material and good resistance to natural and chemical aggression.

TL;DR: In this article, a series of tests were carried out on blocks fabricated with different mixtures to optimise the stabilisers contents, and the results showed the beneficial impacts of cement and quicklime on drying shrinkage, mechanical strengths and water absorption.
Abstract: Adobes are one of the earthen construction techniques adopted in the old Ksour widespread in the desert and rural Algerian areas. The present paper outlines the results of an experimental investigation to assess the influence of stabilisation by cement, quicklime and Date Palm fibres on adobes behaviour. For enhancing the properties of the latter, a series of tests were carried out on blocks fabricated with different mixtures to optimise the stabilisers contents. The key findings show the beneficial impacts of cement and quicklime on drying shrinkage, mechanical strengths and water absorption. The stabilised adobes with 10% cement provided the lowest shrinkage and highest mechanical resistances, whilst those with 10% quicklime offered the highest water absorption resistance. The inclusion of Date Palm fibres up to 0.5% had a mutable effect on mechanical strengths, a positive effect on shrinkage, but negative effect on water absorption of the blocks.

TL;DR: An overview of the extended/generalized finite element method (GEFM/XFEM) with emphasis on methodological issues is presented in this article, which enables accurate approximation of solutions that involve jumps, kinks, singularities, and other locally non-smooth features within elements.
Abstract: An overview of the extended/generalized finite element method (GEFM/XFEM) with emphasis on methodological issues is presented. This method enables the accurate approximation of solutions that involve jumps, kinks, singularities, and other locally non-smooth features within elements. This is achieved by enriching the polynomial approximation space of the classical finite element method. The GEFM/XFEM has shown its potential in a variety of applications that involve non-smooth solutions near interfaces: Among them are the simulation of cracks, shear bands, dislocations, solidification, and multi-field problems.

TL;DR: In this article, the extended and generalized finite element methods are reviewed with an emphasis on their applications to problems in material science: fracture, dislocations, grain boundaries and phase interfaces.
Abstract: The extended and generalized finite element methods are reviewed with an emphasis on their applications to problems in material science: (1) fracture, (2) dislocations, (3) grain boundaries and (4) phases interfaces. These methods facilitate the modeling of complicated geometries and the evolution of such geometries, particularly when combined with level set methods, as for example in the simulation growing cracks or moving phase interfaces. The state of the art for these problems is described along with the history of developments.
