Abstract
In this paper, numerical integration technique of meshfree approach for plate bending analysis is discussed. Stabilized conforming nodal integration (SCNI) is high accuracy and efficient technique for integrating the stiffness matrix in the meshfree approach. However, high gradient region of stresses/strains cannot be accurately represented in the plate bending analysis when SCNI is adopted. To overcome the problem, sub-domain stabilized conforming integration (SSCI) is introduced. Hybrid technique of SCNI and SSCI is also proposed to enhance the accuracy and the computational efficiency. Some plate bending problems are demonstrated and the quantitative evaluation is shown in the numerical examples.
