Finite superelements method for elasticity problems

Abstract

A Fedorenko Finite Superelements Method (FSEM) for 3D linear elasticity problems is considered. We present special weak statement for traces of original problem solution which natural Bubnov‐Galerkin approximation leads to the FSEM. Some applications of the FSEM for the problems of mechanics of composites are considered and results of numerical experiments are presented. Straipsnyje nagrinejamas Fedorenkos baigtiniu superelementu metodas trimačiams tiesiniams elastiškumo uždaviniams. Pasiulytas specialus silpnasis sprendinio pdsako formulavimas, kuris iprasta Bubnovo‐Galerkino aproksimacija susieja su baigtiniu superelementu metodu. Nagrinejami kai kurie baigtiniu superelementu metodo taikymai kompozitu mechanikos uždaviniams. Pateikti skaitinio eksperimento rezultatai. First Published Online: 14 Oct 2010
