A method for improving ray distortion in ultrasonic weld simulation based on a ray-guided Fourier neural operator
Forward simulation of ultrasonic nondestructive testing in austenitic stainless steel welds remains challenging due to the material’s severe anisotropy and heterogeneity. Traditional ray-tracing methods are highly efficient but suffer from amplitude singularities in focal regions, whereas full-wavefield finite element...
