In this study a method was developed to approximate rigid plate loading to be used in GAMES software. When a rigid plate load is acting on the surface of a multilayered system, the resulting interface contact stress distribution is not uniform. Since contact stress distribution between rigid plate and semi-infinite medium is well known, this distribution was approximated using uniformly distributed multiple loads and analysis performed using Games. Results have shown good agreement with the theory for the case of a semi-infinite medium. Furthermore, extension of this method to multilayered system has shown good results if the ratio of the first layer thickness over the loading plate radius is greater than 2enRigid plate loadingElastic multi-layered systemGamesAxi-symmetric analysisConference PresentationMaina, J., Ozama, Y., & Matsui, K.
