Nonlocal strain softening bar revisited

mixed and a modified complementary energy variational formulation for the problem of a continuously supported, axially and transversely loaded beam is presented. The beam and the support are assumed to be linear elastic, and the response of the latter is represented by the current two-parameter model. An equilibrium finite element approach is developed on the ground of the second formulation and the results obtained for some test problems are exposed. 0 1997 Elsevier Science Ltd.
