摘要

This paper aims to characterize the thermo-elastic and fracture properties of an edge-cracked plate with centric hole subject to ambient heat and fluctuated loads. A Radial Point Interpolation Meshless (RPIM) method is first developed and used to estimate the associated stress intensity factor (SIF) for such a complicated problem. It is found that the solution thus obtained by RPIM is somehow more precise than that obtained by the FEM. The influence of edge-cracked locations and lengths on the displacement of the plate that bears fluctuated loads and ambient heat are carefully characterized and presented. Simulation results also reveal that both thermoelastic and fracture properties of the edge-cracked plate with centric hole can be more efficiently and accurately modeled by using the proposed RPIM approach.
