Abstract

The paper presents some aspects of the formulation and numerical implementation of combined mathematical model "elastic body - Timoshenko plate". The variational problem is formulated. The existence of solution of combined model is considered. The numerical investigation of the problem is performer by coupling Direct Boundary Element and Finite Element Methods. Numerical example is presented supporting the analysis.
