NDT of Lattice Sandwich Metal Plate by Using DC Potential Drop Method
To evaluate the feasibility of the Direct Current Potential Drop (DCPD) for NDT of lattice sandwich plate, a code for numerical simulation of DCPD is developed based on the resistance network approach to validate the DCPD for lattice material NDT application. The surface plates and the truss bars are modeled as resistance networks. A lot of numerical simulations are performed by using the developed code for different flaw sizes, electrodes arrangement etc. The results show that the DCPD is suitable for detecting welding flaws in the lattice sandwich plate.
