Local Smoothing Domains Constructed Using Linear Triangular Elements To truncate the infinite problem domain and satisfy the sommerfeld radiation condition, an artificial boundary is constructed by incorporating the mdtn technique. Linear strain fields are constructed within elements without using special smoothing domains. the proposed strain smoothed elements pass patch, isotropic and zero energy mode tests. its improved performance is demonstrated through various numerical examples.
The Smoothing Domain K ω Is Formed By Triangular Elements Download One of the ways to mesh a domain in finite element analysis is using triangular elements. the advantages of using triangular elements is the ability to develop meshing algorithms that can easily mesh any irregular domain with triangular elements. The method is especially robust and effective when the smoothing element discretization is represented by quadrilaterals consisting of four triangular smoothing elements in a cross diagonal pattern. the resulting macro element consists of five nodes, each having three degrees of freedom (dof’s). This work presents a linear smoothing scheme over high order triangular elements within the framework of the cell based strain smoothed finite element method for two dimensional nonlinear problems. We will use this equation for potential energy to develop the stiffness matrix for triangular elements in a thin plate. our goal in this development is to replace both the stress and strain terms with linear equations for nodal displacement.
