A Preliminary Study on Teaching Korean students Chinese tones: Taking Korean High School Students as an Example

Autor: Zefang Xu

Publikováno v: Journal of Contemporary Educational Research. 4

This paper takes the learners who have a one-year experience of learning Chinese in Korean high schools as the investigated and studied sample, concludes the teaching methods of the first, second, third, and fourth Chinese tones, and focuses on the m

ELASTO-PLASTIC BUCKLING OF PRESTRESSED ARCHES

Autor: Amde M. Amde, Amir Mirmiran, Zefang Xu

Publikováno v: International Journal of Structural Stability and Dynamics. :295-313

Intentional buckling as a fabrication technique for arch frameworks results in prestrains at every section of the arch, which in turn affect its strength and stability. A nonlinear corotational straight beam element with elastic, linear strain harden

EFFECT OF GEOMETRIC AND LOADING CONDITIONS ON STABILITY OF PRESTRESSED ARCHES

Autor: Zefang Xu, Amde M. Amde, Amir Mirmiran

Publikováno v: International Journal of Structural Stability and Dynamics. :509-526

Geometric and loading conditions affect stability and strength of arch frameworks. Prestressed arches that are made by buckling of flat struts into shape are more sensitive to these parameters. Most studies on prestressed arches are limited to the in

A New Approach for the Numerical Integration of Nonlinear Dynamic Systems

Autor: Zhi Xiao Su, Ray P. S. Han, Zefang Xu, Zhao Chang Zheng

Publikováno v: Dynamics, Acoustics and Simulations.

In this paper, the exact solution of a linearlized equation is employed as initial conditions for the next timestep in the numerical integration of the end displacement and velocity. This exact solution is calculated by means of the Duhamel integrati

Looping behavior of arches using corotational finite element

Autor: Zefang Xu, Amir Mirmiran

Publikováno v: Scopus-Elsevier

Buckling of arches is studied using a corotational finite element model in conjunction with a modified Riks-Wempner technique. The corotational formulation allows for separation of rigid body displacements from deformation displacements of the elemen
