    Zapis warunku plastyczności w języku skryptowym FlexPDE oraz FLAC 2D
    (2008) Kozubal, Janusz; Wyjadłowski, Marek
    In the paper the describing of linear-plastic material behaviour in Finite Elements codes: FlexPDE and MRS FLAC is presented. The discussion is restricted to linear elastic-perfectly plastic material, two-dimensional plane strain and associated flow rule. For describing linear-elastic material behaviour (for general stress states): stress-strain behaviour in elastic range, yield function or failure function, flow rule, definition of strain hardening (softening) are needed. In the solution the tension stresses are limited and showed like convex multi segment line.
