| Abstract: | In this paper, a penalty function approach to introduce the stress equilibrium conditions in isoparametric hybrid finite element analysis is suggested. The application of penalty function methods in plane quadrilateral isoparametric hybrid stress element is investigated and a method useing separated penalty parameter is presented. Numerical examples show that the proposed method is very effective to overcome the influences of element distortion. |
