| Abstract | A nine- node finite element f or plate bending application is developed by assumed shear strain based on the new mixed formulation 1 0 • This formulation is de rived under the Mindlin plate theory and using the modified Hellinger-Reissner principle with independent trans verse shear strain . By dividing the assumed strains into its lower order part and higher order part , the present element can be more efficient in computation than the element which is developed by the conventional mixed formulation. The investigation are made on five interesting points with numerical examples. The results confirm that the present element an produce good accurate results without transverse shear locking for the wide range of length to thickness ratios. Th e appropriate choice of higher order terms in the independent shear can suppress the undesirable kinema tic mode. Further more the element is relatively in sensitive to geometric distortion and it has a good mesh convergence. |
