    FETI-based Homogenization of Composites with Perfect Bonding and Debonding of Constituents

  • Original language description

    The present paper deals with the homogenization of composite materials with periodic microstructure. Emphasis is put on mathematical modeling of imperfect bonding between linearly elastic constituents. Elements of homogenization theory are introduced, together with the Unit Cell problem governing the macroscopic response of the equivalent homogeneous body. Numerical resolution of mathematical and physical problem of homogenization is based on the Finite Element Tearing and Interconnecting (FETI) method,extended to cover both cases of the perfect bonding and debonding of individual constituents. It is demonstrated that FETI allows very efficient treatment of the conventional homogenization problem for composites with the limit zero as well as infinitevalues of interfacial compliance. Verification of the method is performed using selected data available in open literature.

    Homogenizace kompozitů s perfektním spojením a rozpojením složek založená na metodě FETI

  • Czech description

    Příspěvek se zabývá homogenizací kompozitních materiálů s periodickou mikrostrukturou. Je zaměřen na matematické modelování nedokonalého rozhraní mezi lineárně pružnými složkami. Je představen teoretický základ homogenizační teorie periodických mikrostruktur. Numerické řešení matematicko-fyzikálního problému je založeno na jedné z metod doménové dekompozice - Finite Element Tearing and Interconnecting (FETI) method. Je řešen případ dokonalého spojení a dokonalého rozpojení složek a z práce je zřejmá vhodnost použití metody FETI pro oba případy.
