Finite Element Method

Distribution of electromechanical field near electrode tips is closely related to the reliability of ferroelectric multilayer actuators. In this paper, the deformation and stress concentrations around the electrode tip in two multilayer actuator designs, partially and fully cofired, are investigated by means of experimental measurement and numerical simulations. The digital speckle correlation method (DSCM) is used to measure the full displacement field near the electrode tip with the high spatial resolution.

I thought the mechanics community would be interested in the course notes of

Prof. K. J. Bathe on "Finite Element Analysis of Solids and Fluids". This

course was taught at MIT and now is available freely through MIT Open

In the finite element analysis of a transient problem, the usual procedure is to discretize the space (domain) using finite elements, while in the time direction, a time-stepping scheme based on finite differences is used. Is it possible to use a finite element type discretization in time also?  Is there any work done in this manner?
