Reliable solution of an elasto-plastic Reissner-Mindlin beam for Hencky’s model with uncertain yield function. (English) Zbl 1042.74533
Summary: We apply the method of reliable solutions to the bending problem for an elasto-plastic beam, considering the yield function of von Mises type with uncertain coefficients. The compatibility method is used to find the moments and shear forces. Then we solve a maximization problem for these quantities with respect to the uncertain input data.
