Abstract Two new finite elements are developed for the Mindlin theory plate bending problem. The formulation is based on the modified Hellinger‐Reissner principle with independent transverse shear strains. Numerical examples indicate that, with properly assumed transverse shear strains, these new elements designated as PLAT8 and PLAT8H do not exhibit locking effect even for very thin plates.
