... using the GUW-based NDE methods. The work began with the preparation of the welded test plate and exposure to simulated waste tank environments to initiate SCC, and conducting finite element analysis (FEA) to predict the generation and growth of SCC. The FEA simulated the exact welding process and used...

.... A finite element analysis of an axially loaded rail in contact with an L-shape transducer was formulated by coupling the meshed rail along with the Eq. (8) of the chain particles. In this analysis, the equation of motion of the beam is as follows: (11) u ¨ ( t ) = M r g − 1...

... kilohertz or megahertz for detecting defect/damage effectively. In this regard, numerical simulation using finite element analysis (FEA) offers a powerful tool to study the interaction between wave and defect/damage. Nevertheless, the simulation, based on linear/quadratic interpolation, may be inaccurate...
