✦ Synopsis

Special quadratic isoparametric elements with mid-side nodes at the quarter point have great promise in linear fracture mechanics of two-and three-dimensional problems. It was shown that they possess the required singularity of i//r [1,2]. In addition, they possess rigid body motion and constant strain modes.
