Numerical results for the inhibited hyperbolic paraboloid

We present here a series of numerical tests concerning hyperbolic inhibited shells. The subject is to approximate the normal component of displacement with the help of Ganev-Argyris triangles when the thickness (epsilon SE ar row 0). We then deal with the membrane limit problem (epsilon = 0) in order to compare these results with the last one. The tests show that for all fi xed epsilon there exists a best non-trivial mesh step size h(0) and (epsilo n SE arrow 0) involves (h(0) SE arrow 0). These tests are concerned with a totally clamped hyperbolic parabolic shell. (C) Academie des Sciences/Elsev ier, Paris.
