Determination of the Vlasov foundation parameters - quadratic variation of elasticity modulus - using FE analysis

The objective of this research was to determine the Vlasov soil parameters for quadratically varying elasticity modulus Es(z) of the compressible soil continuum and discuss the interaction affect between two close plates. Interaction problem carried on for uniformly distributed load carrying plates. Plate region was simulated by Kirchhoff plate theory based (mixed or displacement type) 2D elements and the foundation continuum was simulated by displacement type 2D elements. At the contact region, plate and foundation elements were geometrically coupled with each other. In this study the necessary formulas for the Vlasov parameters were derived when Young
