Static And Dynamic Response And Its Control Of Smart Rubber Components Using Nonlinear Finite Element Analysis: .Popularity Of Inflatable Structures Has Increased Rapidly Due To Their Wide Applications In Many Fields E.G., Civil Engineering, Architecture, Vehicle And Aerospace Engineering. In This Context, Rubber-Like Materials Play An Important Role For Their Unique Features. Also, There Is A Present Trend To Use Piezoelectric Materials With The Inflatable Structures To Control The Shape And Vibration Of The Same Structures. Thus Modeling Of Piezoelectric Material On Rubber Substrate On Rubber Substrate With Or, Without Visco-Elastic Property Has Been Attracting The Attention Of Researchers. As Rubber-Like Materials Are Mostly Incompressible And Can Withstand Large Deformation, Hence Geometric Nonlinearity Must Prevail. Also, These Exhibit Nonlinear Stress-Strain Relation That Needs Consideration. Therefore, Modeling A Piezoelectric Layer/Patch On A Rubber Substrate By Finite Element Method Including These Nonlinearities Along With Control Strategies Is A Complex Task. But, No Such Work Is Currently Available To The Knowledge Of The Author On Smart Rubber Components. Since Information Or Knowledge Available On The Analysis Of Surface Bonded/Embedded Piezoelectric Layer/Patch On/In An Elastomer Substrate For Static And Dynamic Behaviors Is Scanty, In The Present Investigation, A Nonlinear Finite Element Formulation Has Been Developed, Which Is Then Applied To Analyze The Nonlinear Static And Dynamic Behaviors And Their Control In Flexible Structures Made Of Rubber-Like Materials. Thus, In The Present Investigation, Non-Linear Finite Element Analyses Of Structural Components Made Of Rubber-Like Materials And Smart Rubber Structures Are Studied. For Reasons Described Later In This Work, Rubber-Like Materials Are Modeled By Compressible Hyperelastic Strain Energy Density
