Feasibility of saline soil Reinforced with treated wheat straw and lime
Soils and Foundations, 2012Co-Authors: Shou Xi Chai, Huyuan Zhang, Li WeiAbstract:Saline soils in inshore areas have characteristics that are problematic to engineering such as salt expansion, dissolution and water absorption; therefore, these soils cannot meet the requirements of strength and anti-deformation in construction. A method of reinforcing saline soil with wheat straw and lime was investigated in this study. Specifically, the feasibility of using wheat straw treated with an SH (modified polyvinyl alcohol) agent as reinforcement and the compaction and strength of saline soil Reinforced with wheat straw and lime were investigated. The results indicated that wheat straw treated with SH agent is suitable for use as a Reinforced Material owing to its higher corrosion resistance, tensile force and elongation. Additionally, reinforcement with wheat straw and lime was found to have a positive effect on the mechanical properties of soil. Reinforcement with wheat straw fiber enhanced the strength of soil during the early curing period and reduced the brittle failure problem associated with lime soil. Reinforcing soil with wheat straw and lime is an effective method for improving soil in the geotechnical field.

Experimental investigation into shaping particle-Reinforced Material by WEDM-HS
Journal of Materials Processing Technology, 2002Co-Authors: Z. N. Guo, X. Wang, Z. G. Huang, Tai Man YueAbstract:Abstract Particle-Reinforced Material is a kind of difficult-to-machine Material. In general, it is inefficient if conventional methods are used to shape it, with worse surface quality and serious wear of the cutting tool. In this paper, the machineability when the Material is machined by wire EDM is studied. A method of orthogonal design has been adopted to determine the main factors that affect the machining process. The result shows that the electric discharge energy is closely related to machining stability. A good machining effect can be attained when the electrical parameters are properly selected, otherwise, the machining may be unstable resulting in wire breakage.

Polar plasticity of thin-walled composites made of ideal fibre-Reinforced Material
International Journal of Solids and Structures, 2013Co-Authors: Kostas P. SoldatosAbstract:Abstract The present study investigates the influence that polar Material response has on the plastic behaviour of thin-walled structures made of ideal fibre-Reinforced Materials ( Spencer, 1972 ); or, equivalently, on the response of thin-walled fibrous composites within the first branch of the matrix dominated form (MDM) of the bimodal theory of plasticity ( Soldatos, 2011 , Dvorak and Bahei-El-Din, 1987 ). The plasticity studies mentioned above assume that fibres are infinitely thin and, therefore, perfectly flexible. They possess no bending stiffness and, hence, their negligible bending resistance cannot influence the developed stress state, which is accordingly described by a symmetric stress tensor. In contrast, the present study considers that if fibres resistant in bending are embedded in a Material at high volume concentrations, their flexure produces couple-stress and, as a result of this kind of polar Material behaviour, the stress tensor becomes non-symmetric. Under plane stress conditions that dominate behaviour of thin-walled structures, the stress-space and, therefore, conditions of plastic yield and relevant yield surfaces are thus four-dimensional. However, shapes and properties of initial yield surfaces relevant to the f1-branch of MDM are studied comprehensively by considering their projection on particular planes of such a four-dimensional stress-space. It then becomes easier understood that, in the regime of polar Material response, a thin-walled structure made of ideal fibre-Reinforced Material deforms plastically when suitable combinations of shear stress values are reached simultaneously, rather than when only one of two unequal shear stress components reaches some maximum absolute value. Thus, polar Material plasticity dismisses the conventional concept of Material yield stress in shear and replaces it with a pair of two independent yield moduli. Existence of the latter is perceived as a theoretical justification of the expectation that, due to the presence of fibres, two rather than one shear yield parameters of the composite should be present and accountable for. The non-zero values of those parameters are shown to exert paramount influence on the form of the yield surface of the ideal fibre-Reinforced Material of interest.
