Analysis of active vibration control in smart structures by ANSYS

It is possible to model smart structures with piezoelectric materials using the product ANSYS/Multiphysics. In this study, the integration of control actions into the ANSYS solution is realized. First, the procedure is tested on the active vibration control problem with a two-degrees of freedom system. The analytical results obtained by the Laplace transform method and by ANSYS are compared. Th...

Prognostics implementation of electronics under vibration loading

In this paper, a methodology is developed for monitoring, recording, and analyzing the life-cycle vibration loads for remaining-life prognostics of electronics. The responses of printed circuit boards to vibration loading in terms of bending curvature are monitored using strain gauges. An analytical model calibrated by finite element analysis is developed to calculate the strain at interconnect...

Analysis of multi-layered microelectronic packaging under uniformly distributed loading

An accurate estimate of interfacial stresses in multi-layered microelectronic packaging is very important for design and prediction of delamination-related failures. An analytical model for stress analysis of multi-layered stacks, which is based on an extension of Valisetty s model (Bending of Beams, Plates and Laminates: Refined Theories and Comparative Studies, Ph.D. thesis, Georgia Institute...

Vibration Analysis of a Nonlinear Beam Under Axial Force by Homotopy Analysis Method

In this paper, Homotopy Analysis Method is used to analyze free non-linear vibrations of a beam simply supported by pinned ends under axial force. Mid-plane stretching is also considered for dynamic equation extracted for the beam. Galerkin decomposition technique is used to transform a partial dimensionless nonlinear differential equation of dynamic motion into an ordinary nonlinear differenti...
