    Notes: For a quantitative analysis and better understanding of the stress-strain response and theireffects on interface debonding and crack initiation and propagation of alternative hard and softmulti-layers under circumscription loading, to explore methodologies of optimum design of surfacemulti-layers, large strain elasto-plastic finite element method is used to evaluate the mechanicalbehaviors of TiN/Ti multi-layer films on rigid substrate under hard asperity indentation. Theresults show that with the same total thickness of the film, the alternate hard and soft multi-layerswith larger ratio could endure larger circumscription loading, and the different total thickness ofmulti-layers could affect the circumscription loading greatly. So there must be a circumscriptionloading in this multi-layer film structures. Generally speaking, the circumscription loading hassomething to do with the material modulus, the radius of the press-head, the thickness ratio of softand hard layers, and the total thickness of alternate hard and soft multi-layers. For a quantitativeanalysis of this problem, finite element method is utilized to analyze the phenomena of the plasticindentation. According to analysis of the film deformation, the maximum bending stress, and thesurface bending stress, and those parameters that have influence on different alternative films arestudied. The study of this paper is expected to provide some theoretical basis for the optimumdesign of multi-layer film structures

    Experimental Studies on Axially Loaded Concrete Columns Confined by Different Materials (2008)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: The improvement of the load carrying capacity of concrete columns under a triaxial compressive stress results from the strain restriction. Under a triaxial stress state, the capacity of the deformation of concrete is greatly decreased with the increase of the side compression. Therefore, confining the deformation in the lateral orientation is an effective way to improve the strength and ductility of concrete columns. This paper carried out an experimental investigation on axially loaded normal strength concrete columns confined by 10 different types of materials, including steel tube, glass fiber confined steel tube (GFRP), PVC tube, carbon fiber confined PVC tube (CFRP), glass fiber confined PVC tube (GFRP), CFRP, GFRP, polyethylene (PE), PE hybrid CFRP and PE hybrid GFRP. The deformation, macroscopical deformation characters, failure mechanism and failure modes are studied in this paper. The ultimate bearing capacity of these 10 types of confined concrete columns and the influences of the confining materials on the ultimate bearing capacity are obtained. The advantages and disadvantages of these 10 types of confining methods are compared

    Performance of Polypropylene Fiber and Rubber Powder Improved High Strength Concrete (2008)

    Notes: Based on high strength concrete (HSC), the improved HSC concrete was produced by adding different contents of fine grain rubber particles and polypropylene fibers. The grain size of the rubber particle is 420 m and the rubber content is 1%, 2%, and 3% of the mass of cementitious material respectively. The volume fraction of polypropylene fiber is 0.1%.The performance of HSC, rubber particle improved high strength concrete (RHSC), polypropylene fiber improved high strength concrete (PHSC) and polypropylene fiber hybrid rubber particle improved high strength concrete (PRHSC) before and after high temperature are studied. The investigation methods used are the external surface inspection, weight loss and residual strength testing. The experimental results show that rubber particles can improve the workability of HSC and PHSC under normal temperature. Polypropylene fiber can significantly improve the spalling failure resistance property of HSC and RHSC

    Notes: Abstract A theory of elasticity for the bending of orthogonal anisotropic beams has been developed by analogy with the special case, which can be obtained by applying the theory of clasticity for bending of transversely isotropic plates[1] to the problems of two deminsions. In this paper, we present a method to solve the problems of bending of orthogonal anisotropic beams and a new theory of the deep-beam whose ratio of depth to length is larger. It is pointed out that Reissner’s theory to account for the effect of transverse shear deformation is not very approximate in the components of stress.
