  • Elastodynamic analysis of a propagating finite crack in a micropolar elastic solid

    Creator:
    Han, Seog-young
    Abstract:
    A dynamic propagation of a finite crack of opening mode in a micropolar elastic solid was investigated. By using an integral transform method, a pair of twodimensional singular integral equations governing stress and couple stress was formulated in terms of the displacement transverse to the crack, macro- and microrotations, and...

  • Dynamic finite element analysis of micropolar elastic materials

    Creator:
    Kim, Jong-bum, 1960-
    Abstract:
    In granular or fibrous materials, in which the dimensions of the internal structure can be of the same order of magnitude as major flaws or holes, classical elasticity theory does not consistently provide accurate models of the large stress gradients that may develop. With the incorporation of additional rotational degrees...
