Vibration Control of Structures Utilizing Architectural Walls
A study of architectural walls for energy dissipation and vibration control of buildings in seismic zones is presented. Typical architectural walls exhibit inelastic behavior; however, both the stiiness and energy dissipation capacity degrade after the walls are damaged. Integrating passive damping devices within these walls augments their energy dissipative abilities by widening the hysteresis...
متن کاملUltrasonic Plate Waves for Fatigue Crack Detection in Multi-layered Metallic Structures (preprint)
A representative area of concern for fatigue crack growth in aircraft occurs in multi-layered metallic structures. Ultrasonic plate waves are currently being investigated by multiple initiatives to detect these types of flaws with a minimal number of sensors to enable Structural Health Monitoring (SHM). Previous work has focused on structures with one or two layers, coupled with modeling of the...
متن کاملActive intelligent control of vibration of flexible plate structures
The development of intelligent control approaches for vibration reduction of flexible plate structures are investigated and reported in this thesis. In this work active intelligent control comprises a set of control techniques based on particle swarm optimisation (PSO), real coded genetic algorithm (RCGA) and artificial immune system (AIS). A traditional method of recursive least squares ( U S ...
متن کاملEffect of Thermal Environment on Vibration Analysis of Partially Cracked Thin Isotropic Plate Submerged in Fluid
Based on a non classical plate theory, an analytical model is proposed for the first time to analyze free vibration problem of partially cracked thin isotropic submerged plate in the presence of thermal environment. The governing equation for the cracked plate is derived using the Kirchhoff’s thin plate theory and the modified couple stress theory. The crack terms are formulated using simplifie...
متن کاملVibration, Buckling and Deflection Analysis of Cracked Thin Magneto Electro Elastic Plate Under Thermal Environment
The Magneto-Electro-Elastic (MEE) material exhibits pyroelectric and pyromagnetic effects under thermal environment. The effects of such pyroelectric and pyromagnetic behavior on vibration, buckling and deflection analysis of partially cracked thin MEE plate is presented and discussed in this paper. The aim of the study is to develop an analytical model for the vibration and geometrically linea...
