- Abstract
Additional displacement fields based on internal parameters were used widely in finite element method to increase the order and complementary of displacement polynomials, thus accuracy and insensitivity to mesh distortion of elements can be improved significantly. To ensure that the element could pass patch test, internal displacement field should be formulated without incompatible energy on element's sides. In this paper, based on generalized conforming theory, the second quadrilateral area coordinate method QACM-II was used to develop universal form for plane elements. This universal internal displacement field can be used easily for those plane elements formulated with QACM-I or QACM-II.
