The strongest point about damage identification based on the dynamic measurements, is ability perform structural health evaluation globally. Researchers in last few years payed more attention to indicators modal analysis using either frequencies, mode shapes, or Frequency Response Functions (FRFs). This paper presents a new application of cross-ply (0°/90°/0°) laminated composite plate Force Residual Method (FRM) indicator. Considering single and multiple damages with different levels. As...
In this paper, we present a new application based on Genetic Algorithm (GA) to detect damage in 3D frame structures. Finite Element Method (FEM) is used build models for intact and damaged The identification of formulated as an optimization problem using GA the changes natural frequencies. A structure with two floor used, numerical example, identification. proposed method then applied identify some removed elements. results obtained FEM validated experimental benchmark test eight floors....
In this paper, a new experimental study of the bending static and fatigue behaviors composite material reinforced with 40% by mass short glass fibers (type E) polypropylene matrix is presented. The obtained in form plates an injection process, which inevitably affects distribution therefore behavior studied. To do this, several techniques are implemented on specimens cutting them transverse longitudinal directions. effect aging distilled water at 40℃ mechanical characteristics studied under...
The delamination problem is very important failure mechanism in certain types of composite structures. Detecting this type damage using vibration data currently a interest to the structural health monitoring community. In paper, we used finite element method with embedded interface for analysing damaged laminated flexibly modal method, which analysis related modelling, detect and localize delamination. Several numerical examples are presented order evaluate accuracy approach.
Structural Health Monitoring (SHM) and impact monitoring of composite structures have become important research topics in the recent year. In this research, a non-destructive vibration-based damage detection method is formulated using Genetic Algorithm (GA) compared with classical method. The robustness reliability capability to locate estimate severity damage, based on changes dynamic characteristics structure, investigated. objective function for identification problem established by...
In this paper, the problem of using measured modal parameters to detect and locate damage in beam composite stratified structures with four layers graphite/epoxy [0°/902°/0°] is investigated. A technique based on residual force method applied structure different boundary conditions, results detection for several cases demonstrate that as index, location can be identified correctly extents estimated well.
Structural damage, whether visible or hidden, is an inevitable occurrence in all structures, machines, and tools, arising from factors such as machining processes, wear, impact. Over the years, significant efforts structural dynamics have been devoted to evaluating reconciling numerical models with experimental data accurately detect quantify damage. This study presents a comprehensive approach identifying quantifying damage multilayer composite beams by first assessing global modal...
