摘要：This work shows a numerical simulation using a finite element code of the ultrasonic wave propagation through the concrete, to measure stress values relating speed changes of the wave with modifications of Young module. The simulation is
performed for isotropic elastic material (the sample has not been charged) assuming plane stress conditions to reduce a two dimensions the problem of wave propagation.
The entering of the ultrasonic wave will be represented prescribing displacement rate histories on some nodes that represent the transductor size on the left bound of the sample.
