Elimination of spurious pressure and kinematic modes in biquadratic nine-node plane element. (English) Zbl 0846.73070
The authors propose \(Q9/3p\) elements which are free from spurious pressure. Complete theoretical development has been made, and the conclusions are illustrated by a number of numerical experiments together with the description of the program code.
