This study focuses mainly on the normal stresses that are caused by applied forces. As a case study, the present work aims at investigating the bi-dimensional contact mechanics of wavy cosinusoidal anisotropic finite planes. To achieve this objective, results on the displacement and stress component are first calculated with the help of the Lekhnitskii formalism.

A finite element model using a multi-fiber approach is proposed in this paper for the analysis of reinforced concrete (RC) members using fiber-reinforced polymer (FRP) reinforcements, with a specific focus on the effect of pure torsion. The main objective of this study is to develop a numerical finite element model to predict the behavior of RC beams with FRP reinforcement under pure torsional effects.

High-volume fly ash mortar is considered a "green" material, a sustainable development solution for the construction industry, in which the fly ash replacement Portland cement content is over 50%. However, this material has the major disadvantage of slow strength development, especially at an early age, which limits its applicability.

In recent years, the prediction of the effective transport properties have received a great number of investigations. The present work is dedicated to determining the effective permeability of two-dimensional (2D) doubly porous materials made of an isotropic permeable solid matrix in which elliptical shaped pores of any size are embedded.

Wood, an environmentally friendly construction material, is characterized by a critical attribute that significantly influences its mechanical properties and durability: its moisture absorption behavior. This study expands upon an existing one-dimensional model to develop an innovative two-dimensional numerical framework for simulating moisture propagation within wood.

Recently, the phase field modelling is widely used to model and simulate material damage. In present work, we present a framework of the topology optimization combined with the phase-field modelling with/ without interfacial damage for optimizing the damage resistance of the inclusion-matrix composites.

The phase-field method has become a robust tool to describe the complex crack nucleation and propagation in heterogeneous materials. In these materials, an interaction between bulk brittle damage and interfacial damage through the splitting the strain tensor into a bulk strain part and a jump strain part at the interfaces.

In recent times, the phase field method is a robust simulation tool that can predict crack formation and propagation in structures. In brittle and quasi-brittle materials, the strain tensor is decomposed into negative and positive parts corresponding to the compression and tension behaviors when the structure is loaded.

In this communication, we synthesized the composite of MoO3/TiO2 with hierarchical electronic structure via the facile impregnation combined with calcination of precursors. Beside the forming of composites, the asprepared samples were in a desire of Mo-doping into TiO2 lattice, due to the smaller radius of Mo+6 compared to Ti+4, leading to the reduction of the band gap.

Mature women’s fashion, for those aged 35 years and older, seems underrepresented in the Australian marketplace and media. International research suggests similar circumstances prevail for older women abroad but there are conditions unique to Australia’s garment industry that exacerbate and frustrate mature consumers further. This research investigates factors affecting midlife consumer’s fashion in Australia and explores the lifestyle interests and expectations of mature consumers.

In recent years, a raising problem encountered by high school students in general and rural ones in particular is extremely bad speaking skill. This leads to a serious subsequence is that quality of students is low as well as learning and teaching have to face to many difficulties due to the reason that speaking skill is an essential instrument when learning communication in any another language. The problems were related to speaking materials, students’ physical limits, and supporting equipment.
