Effect of Surface Roughness on Ultrasonic Testing of Back-Surface Micro-Cracks

Effect of Surface Roughness on Ultrasonic Testing of Back-Surface Micro-Cracks

Surface roughness is one of the main factors that affect the ultrasonic testing of micro-cracks. This article theoretically analyzes the relationship between the changes in the energy intensity of crack echo waves and roughness-modified transmission coefficients. A series of simulations are carried...
