Many of existing concrete bridges are in a poor or in a very poor condition. For the design of the bridge rehabilitation it is very important to find out the actual status and extent of damage of the bridge. To determine the material characteristics of concrete and fault detection can be used non-destructive and destructive methods. Application of non-destructive methods extends possibilities of the investigations. These methods do not damage the structure and can be applied repeatedly.

Majority of structural materials can be categorized, from the material failure point of view, as quasi-brittle or ductile. They are characteristic by formation and propagation of sizeable nonlinear zone in front of the tip of a defect that causes violation of their integrity. Capturing the nonlinear zone influence is the key to significant improvement in accuracy of the failure description. Nonlinear zone characterization will be conducted via advanced experiments (AE, X-ray) and simulations.
