UNILATERAL PLATE CONTACT WITH THE ELASTIC PLASTIC WINKLER-TYPE FOUNDATION

In this work contact problems of a plate with the elastic-plastic Winkler-type foundation has been solved. An unilateral character of bonds between plate and foundation has been taken into consideration. The effect of friction forces in the contact plane has been neglected and an incremental approach has been applied. An incremental problem has been formulated in a variational manner and solved by use of the finite element method. The results of numerical calculations for rectangular plates subjected to the simple and complex load processes have been presented.
