Consistent Asymptotic Expansion Multiscale Analysis of Heterogeneous Thin Plate and Shell Structures

板壳结构是工程领域应用非常广泛的一种结构形式。复合材料可以充分利用各相材料的优点，因而被越来越广泛地应用到板壳结构中，组成复合板壳结构。为了更好地分析设计复合板壳结构，需要研究其微观结构对材料宏观性能的影响。但是，复合板壳结构的微观结构通常仅在面内呈周期性排列，在板壳厚度方向满足平面应力条件，因此三维渐进展开多尺度分析并不适用于该类结构。本文采用能够反映该类结构特点的一致渐进展开多尺度方法，将薄板壳的微观结构和宏观结构间的应力变形联系起来，建立不同尺度间的联系，系统地研究薄板壳结构的弯曲性能，有重要的理论研究和工程应用价值。 文中分析了薄板位移场的渐进展开表达式，在三维弹性理论的框架下建立了...Plate and shell structures have been widely used in engineering practice. Since composite materials combine the advantages of different phase of materials, they are well utilized to form composite plates and shells. For the composite plates and shells, it is crucial to efficiently study the macroscopic structural response as well as the microscopic stress-strain behavior for safty evaluation and e...学位：工学硕士院系专业：建筑与土木工程学院_工程力学学号：2532011115172

Hermite reproducing kernel meshfree thermal buckling analysis of Euler-Bernoulli beams with elastic foundation

Conference Name:2014 International Conference on Mechanics and Mechatronics, ICMM 2014. Conference Address: Xi'an, Shanxi, China. Time:May 9, 2014 - May 11, 2014.Adavance Information Science Research Center; Donghua University; Guangdong University of TechnologyThe Hermite reproducing kernel meshfree method is employed for the stability analysis of Euler-Bernoulli beams with particular reference to the thermal buckling problem. This meshfree approximation employs both the nodal deflectional and rotational variables to construct the deflectional approximant according to the reproducing kernel conditions. In this paper, we apply this HRK meshfree method to the thermal buckling analysis of Euler-Bernoulli beam on elastic foundation. By comparison to the Gauss Integration method, HRK meshfree method shows much better solution accuracy. ? (2014) Trans Tech Publications, Switzerland

Seismic analysis of a water release integrated structure part II: Time history analysis of service bridge pier structure

Conference Name:2nd International Conference on Mechanical Engineering, Materials Science and Civil Engineering, ICMEMSCE 2013. Conference Address: Beijing, China. Time:October 25, 2013 - October 26, 2013.In this study the three dimensional finite element method is employed to analyze the time history response for the service bridge pier of a water release integrated structure under the minimum operation level and the normal storage water level in maximum design earthquake load condition. The Mexico seismic curve is provided to perform the time history analysis for the present project. The temporal integration of time history analysis is carried out by the Newmark method and the stress, deformation results of the service bridge pier structure is discussed in detail. ?

An assessment of damage to large-scale basement slab caused by groundwater and expansive soil

Conference Name:3rd International Conference on Civil Engineering, Architecture and Building Materials, CEABM 2013. Conference Address: Jinan, China. Time:May 24, 2013 - May 26, 2013.Cracking damage is a common phenomenon in large-scale concrete structure. But for the underground structure it is not permitted because crack will cause heavily damage and other disasters. With the aid of finite element method for deformation and stress field simulation, a detailed study is carried out for a large area foundation slab of an underground parking lot. The foundation soil condition and the hydrogeological condition are the principal influence factors that result in the cracking problems. The simulation results illustrate that the combined effects of foundation settlement and larger groundwater pressure cause the foundation slab cracking and the existence of expansive soil indeed exacerbates the problem. ?
