Vibration of visco Elastic plate with variable Geometry

Abstract

the study focus on VIBRATION OF VISCO-ELASTIC Vibration is the periodicity of mechanical oscillation through an equilibrium point. newlineIn some cases vibration phenomena is desirable, such as in machine tools, mobile newlinephones, loudspeaker and production lines. In most of cases, however the vibration newlineis undesirable such as in mechanical systems because of wastes of energy, reduces newlineefficiency, produced unwanted sound and may be dangerous in some scenarios. For newlineexample, passengers smooth ride in cars, motorcycles and aircraft is greatly affected newlineby the vibrations due to such aero elastic effects or road conditions. By eliminating newlinevibration or reduce vibration in some cases, we can save human lives (to control newlinevibration in civil engineering structure) and make life better. newline
