This paper presents an application of DKMQ24 element for error estimation using error estimator Z2 and various recovery methods such as Averaging (AVR), Projection (PROJ) and Superconvergent Patch Recovery (SPR). The stresses found by using these recovery methods will be compared to the reference solution. We found that Averaging and SPR method gave better results compared with the Projection method.
