Fatigue of Fillet-welded Joint Assessment by the FEA Simulation of Damage Accumulation

An approach based on the FEA simulation of fatigue damage accumulation is suggested and applied to evaluate the crack initiation at the cavity and propagation in the non-continuous fillet-welded joint. The crack initiation at the cavity, its three-dimensional shape formation and evolution are simulated taking into account the elastic-plastic cyclic deformation of weld material until almost complete failure of the joint.

Substantive provisions of Numeral-analytical boundary elements method

Substantive propositions of the new method of structure calculation got the name "Numeral-analytical boundary elements method" offered by authors are brought. A method consists of development of the fundamental system of decisions (analytically) and Green functions (also analytically) for every examined task.
