摘要：

We present a new asymptotic-numerical method for the buckling analysis of imperfect elastic structures. It improves the classical estimate given by the theories of postbuckling or of perturbed bifurcation. By this way, we are able to compute numerically a class of nonlinear problems by inverting only one stiffness matrix. © 1990.
