Numerical Analysis of Temperature Influence on Transverse Cracks in Concrete Box‐Girder Bridges
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 Concrete box‐girder bridges are widely used in China. During several routine inspections of two‐year‐old highway bridges of this type in the China Central Plains region, we found that transverse cracks are widespread on the bottom flanges of those box girders, mainly distributed in the area of 1/4L to 3/4L of the span.

Numerical Solution of Sine‐Gordon Equation with the Local Kriging Meshless Method
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 This paper develops a local Kriging meshless solution to the nonlinear 2 + 1‐dimensional sine‐Gordon equation. The meshless shape function is constructed by Kriging interpolation method to have Kronecker delta function property for the two‐dimensional field function, which leads to convenient implementation of imposing essential boundary conditions ...

The Improved Moving Least‐Square Ritz Method for the One‐Dimensional Sine‐Gordon Equation
Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014 Analysis of the one‐dimensional sine‐Gordon equation is performed using the improved moving least‐square Ritz method (IMLS‐Ritz method). The improved moving least‐square approximation is employed to approximate the 1D displacement field. A system of discrete equations is obtained by application of the Ritz minimization procedure.

The Interpolating Element‐Free Galerkin Method for 2D Transient Heat Conduction Problems
Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014 An interpolating element‐free Galerkin (IEFG) method is presented for transient heat conduction problems. The shape function in the moving least‐squares (MLS) approximation does not satisfy the property of Kronecker delta function, so an interpolating moving least‐squares (IMLS) method is discussed; then combining the shape function constructed by the ...
