| Abstract: | In this paper,we discuss noncoaforming finite element approsimatian for the variationsl inequality with clamped supported boundary and constraint on displacement obstacle. In the appropriate assumptions on regularity, we obtain error estimate for corresponding finite element discrete problera as follows:
for a kind of nonconforming finite element which includes Morley's' element,the first and second kind of Fraeijs de Veubeke's element, Adini's eleinent,Zienciwez's element,and the incomplete biquadratic nonconforming plats element(WS's element). |
