| Summary: | This paper presents an
application of the Discrete Kirchhoff-Mindlin Triangular (DKMT) element for error estimation
in composite structures. The DKMT element passed the patch tests and gave good results in many plate
bending applications. The DKMT element formulation in composite application uses the same technique as the Discrete Kirchhoff-Mindlin
Quadrilateral (DKMQ) composite introduced. The benchmark tests for composite plates have been analyzed, as
validation, using the methods
employed by Srinivas (1973) and Pagano (1970). The DKMT plate bending element gave a good performance in
convergence tests and can be used as one of tools in analyzing composite structures. Moreover, error estimation
using various recovery methods such as Averaging, Projection and
Superconvergent Patch Recovery (SPR) has been studied. All recovery methods
used give similar results. |
