描述The present short monograph concerns analytic and semi-analytic techniques for finding an approximate value of the limit load. The limit load is an essential input parameter of flaw assessment procedures. In most cases, finding the limit load involves some numerical calculations of different levels of complexity, including numerical minimization of functions of one or several arguments, the slip-line technique and the finite element method. This book shows in particular how to use singular behavior of the real velocity field in the vicinity of bi-material interfaces in kinematically admissible velocity fields to increase the accuracy of upper bound solutions. An approach to recalculate the limit load for a class of structures with defects with the use of its value for the corresponding structure with no defect is discussed. The upper bound technique is applied to evaluate the limit load of overmatched and undermatched welded joints with cracks subject to various loading conditions of practical importance in conjunction with the aforementioned special techniques.

Upper Bound Theorem,ples associated with the lower bound and upper bound theorems. The latter is used in the present monograph to estimate the limit load for welded structures with and with no crack. A proof of the upper bound theorem for a wide class of material models has been given by Hill (1956). The only reliable

By assumption, the constraints imposed require that the rigid blocks of base material move along the line of action of the forces. A crack is entirely located in the weld. Edge cracks are excluded from consideration. The width of the plate is denoted by 2., its thick

Plane Strain Solutions for Highly Undermatched Specimens in Bending,elds are adopted. One of the fields results from an exact analytic solution for deformation of a plastic wedge between two rotating plates. The other kinematically admissible velocity field is obtained using simple assumptions and the known asymptotic singular behaviour of the real velocity field ne
