Theoretical and Experimental Investigation of Non-linear Vibration Response of an IPMC Actuator Subjected to Alternating Electric Potentialf
Abstract: The precise predication of stable and unstable zone for an applied excitation voltage and frequency is of importance in many micromechanical systems utilizing ionic polymer metal composite (IPMC) as the actuator. A linear dynamic model thus will no longer be valid for IPMC actuator having low thickness and thus more flexible. In this article, non-linear vibration characteristics of a silver (Ag) based IPMC actuator is studied under alternating electric potential …

“FORCE-DISPLACEMENT TRADE OFF” OF RCC BUILDING LOCATED AT VARIOUS SEISMIC ZONES AND SITE CONDITION ADOPTING TIME-HISTORY ANALYSIS
Abstract: Earthquake-resistant or aseismic design are considered to protect buildings to some or greater extent from earthquakes. The force-displacement trade off of structures located in various seismic zones are different in nature depending on intensity of earthquake. No structure can be fully immune to damage from earthquake, the vulnerability can be reduced for safety and durability. The force-displacement behavior of a particular structure can be modified to withstand seismic occurrence preventing …
