On the project

Description in English
Stress and strain computational modelling of the compound vessel of mixed construction with the supporting wound part, exhibiting different radial and tangential stiffness. Manufacturing as well as assembly imperfections lead to the s.c.structure anisotrophy of the transversal orthotropic type. The problem solution will be performed on two computational levels, first one in the analytical form for the equivalent cylindrical model of the compound vessel and second one in the numerical form for the axisymmetrical computational model with the help of the finite element method (FEM). The own FEM code PROKOP, being developed for the solution of selected technological operations and processes, will be enhanced, to be able to solve the orthotropic problem. The proposed method will also make possible the strength optimization of the whole compound vessel including the assesment of the ribbon prestressing during the winding process. The transversal orthotropic material model of the wound part can analyze the i
