Author:Long, Craig S; Loveday, Philip W; Groenwold, AADate:12 Mar 2006Several new planar four node piezoelectric elements with drilling degrees of freedom are presented. The authors begin by deriving two families of variational formulations accounting for piezoelectricity and in-plane rotations. The first family ...Read more
Author:Wilke, DN; Kok, S; Groenwold, AADate:Feb 2013Shape optimization strategies based on error indicators usually require strict error control for every computed design during the optimization run. The strict error control serves two purposes. Firstly, it allows for the accurate computation ...Read more
