Ap plications in FEM modeling\nby Vladislav Mantič (University of Sevill a) as part of Nečas Seminar on Continuum Mechanics\n\nLecture held in Roo m K3\, Faculty of Mathematics and Physics\, Charles University\, Sokolovs ká 83 Prague 8..\n\nAbstract\nLinear-elastic antiplane-strain problems g overned by the 2D Laplace equation are considered in domains with corners and cracks. First\, power-logarithmic stress singularities in Neumann-Robi n BVPs in infinite corner (polar sector) type domains are studied. Asympto tic solutions given by a double asymptotic series with the main and the as sociated shadow terms are presented. An application of such an asymptotic series to the numerical solution of the BVP of a crack in a thin adhesive interface layer modeled by the spring interface is shown by implementing a finite element method (FEM) procedure. Second\, similar asymptotic analys is of power-logarithmic stress singularities in Dirichlet-Robin BVPs in in finite corners with a power-law variation (with the distance to the corner apex) of the governing coefficient in the Robin boundary condition is pre sented. An application of such an asymptotic solution to the BVPs of bridg ed cracks with a power-law variation of the stiffness of linear-elastic sp ring distribution is presented. Finally\, a power-logarithmic stress singu larity in a Dirichlet-Ventcel BVP in half domain is studied by a similar a symptotic procedure. An application of this asymptotic solution to the FEM solution of a BVP with a finite and open Gurtin-Murdoch material surface is presented.\n LOCATION:https://researchseminars.org/talk/NSCM/147/ END:VEVENT END:VCALENDAR
