CONFORMING TRIANGULAR MEMBRANE ELEMENT WITH VERTEX ROTATIONAL FREEDOM FROM GENERALIZED COMPATIBLE CONDITION

    Graphical Abstract
    • Abstract
  • Two triangular membrane elements arc derived from the concept of generalized conforming finite element by means of introducing vertex rigid rotational freedom. The elements, with simple formulation, pass the patch test. Numerical results exhibit that the accuracy obtained with present elements is exceptionally good.
