Thank you Dear Professor,
I've obtained the copies of forementioned nomenclatures, although I'm very familiar with thick plate theory I found it bit a hard to understand how the mixed formulation is performed. The procedure really resembles to that of Henschel Tocher triangular element but the integration part is different. In order to understand it throughly I should study it a bit more and I'll need time which is my burden.
Actually, my main goal was to implement the plate on elastic foundation , starting from the simplest to the hardest theory such as Winkler springs, 2 parameter Vlasov model and finally half-space theory. Could you shed some light on that issue, is that triangular element is suitable for serving that purpose of modelling the plate on elastic foundaiton?
Your help will be appreciated,
