Project Overview
In this example, the location of a crack is determined using Lamb waves in Abaqus.
Lamb waves are guided waves that propagate through thin plates and can be used for damage detection and crack localization. In this simulation, a Lamb wave is applied to an aluminum plate containing a crack, and the resulting wave propagation is investigated.
Plate Geometry and Crack
The plate has a length of 500 mm and a width of 40 mm. The plate thickness is 1 mm.
A crack is introduced into the aluminum plate. The objective of the simulation is to identify the location of this crack based on the propagation and response of the Lamb waves.

Lamb Wave Application
A Lamb wave is applied to the aluminum plate and propagates through the plate.
When the wave encounters the damaged region, its propagation behavior is affected by the presence of the crack. The wave response can therefore be used to obtain information about the location of the damage.

Wave Propagation
The propagation of the Lamb wave through the plate is monitored during the Abaqus analysis.
The wave travels through the plate and interacts with the cracked region. By analyzing the wave response, the position of the damaged region can be identified.

Sensor Response
A sensor is used to record the horizontal displacement produced by the propagating Lamb wave.
The recorded displacement response provides useful information about the arrival and propagation of the wave and can be used to determine the location of the crack.

Crack Location Detection
The main objective of the simulation is to use the Lamb wave response to determine the location of the crack.
Changes in the wave propagation and the displacement response recorded by the sensor provide information about the presence and location of the damaged region in the plate.
