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 ...

Numerical Simulation of Mesodamage Behavior of Concrete Based on Material Point Method
Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020 Concrete consists of coarse aggregates, mortar matrix, and interfacial transition zone (ITZ) between them at the mesoscale. Considering these three phases, many numerical tests have been conducted to study the mesodamage behavior of concrete, in which a variety of numerical methods have also been adopted.
