Elimination of spurious kinematic modes in hybrid equilibriumelements

Research output: Contribution to conferenceOther

Abstract

Hybrid stress elements are proposed as alternative to standard finite elements for linearand non linear analysis. Hybrid stress formulation is developed in a rigorous mathematical settingand an original approach for elimination of spurious kinematic modes is presented. Hybrid equilibriummethod is compared to classical displacement based method by linear elastic analysis of somewell known structural examples.
