Titel / Title: Damage Assessment in Thin Materials: Finite Element Investigation
Abstrakt Abstract:

This thesis describes the process of detection, and if possible, also localization of the damage in non structural sheet-like materials. Simulation and analysis is carried out in ABAQUS with a FE model that has the same dynamic characteristics as the corresponding real material. Three types of damage forms are investigated: crack, hole and local weakness. Results presented in the report show that global damage detection and localization in sheet-like structure by monitoring changes in the modal parameters is possible. Based on the results, this thesis provides a basis for development of global non-destructive health monitoring methods for materials having no bending stiffness.
