WebThus, Reissner and Mindlin theories have assumed same values for o, at the faces or at x3 equal to +h/2, but Reissner's theory concerned about 033 distribution on the thickness. Mindlin showed [3] that in his theory only the linearlv weighted average effect of 033 was neglected rather than 033 itself with
