Vibration based Structural Health Monitoring of a Composite Plate Structure with Multiple Stiffeners
نویسندگان
چکیده
A vibration based damage identification method is investigated experimentally. The dynamic response of an intact and a locally damaged 16–layer unidirectional carbon fibre PEKK reinforced plate structure with two stiffener sections is considered. A forced–vibration set–up, including a laser vibrometer system, is employed to measure the dynamic behaviour. The feasibility of the two–dimensional Modal Strain Energy Damage Index algorithm to detect and localize impact induced defects is demonstrated.

Vibration based structural health monitoring of a compos- ite plate with stiffeners
A vibration based damage identification algorithm is implemented to assess the damage of a thin–walled composite structure. The structure analysed is a skin with stiffeners, as frequently applied in aircraft components. Both experimental and numerical studies on a single composite skin–stiffener structure showed that the modal strain energy damage index (MSE–DI) algorithm is a suitable method f...
متن کاملDevelopment of a Damage Quantification Model for Composite Skin-Stiffener Structures
The development of a model-based approach for a damage severity assessment applied on a complex composite skin structure with stiffeners is presented in this paper. Earlier investigations on composite structures with stiffeners revealed that a vibration based structural health monitoring approach, employing the Modal Strain Energy Damage Index (MSE-DI) algorithm can detect and localise delamina...
متن کاملHealth Monitoring of Welded Steel Pipes by Vibration Analysis
In the present work, structure health monitoring (SHM) of welded steel pipes was used to diagnosis their state via vibration based damage detection techniques. The dynamic quantities such as Frequency Response Functions (FRFs), mode shapes and modal parameters from structural vibration to detect damage were measured, set on linear averaging mode, with a maximum frequency of analysis of 3.2 kHz....
متن کاملFree Vibration of Lattice Cylindrical Composite Shell Reinforced with Carbon Nano-tubes
The free vibration of the lattice cylindrical composite shell reinforced with Carbon Nano-tubes (CNTs) was studied in this study. The theoretical formulations are based on the First-order Shear Deformation Theory (FSDT) and then by enforcing the Galerkin method, natural frequencies are obtained. In order to estimate the material properties of the reinforced polymer with nano-tubes, the modified...
متن کاملVibration analysis of a rectangular composite plate in contact with fluid
In this paper, modal analysis of the fluid-structure interaction has been investigated. Using classical laminated plate theory, a closed form solution for natural frequencies of FSI is extracted. For fluid, homogenous, inviscid and irrotational fluid flow is assumed. Then, a combined governing equation for the plate-fluid system is derived. In order to validate the equations and results, they a...
