✦ Synopsis

We study the bending limit problem of shells in relation to the membrane locking, encountered in "nite element computation of non-inhibited very thin shells. Using a new approach of the theory of inextensional displacements (or in"nitesimal bendings) we solve the bending limit problem in the case of a clamped hyperbolic paraboloid. We then use this solution to validate computations which can be used as benchmarks for the membrane locking. Such con"guration, non-inhibited hyperbolic very thin shells, usually lacks numerical &validation'.
