Abstract

For various configurations examined in a series of fatigue experiments on thin-walled tubes under
tension and torsion, the experimental results – crack path, crack growth life, near crack tip deformations, and
crack closure – are measured and compared to the results of some numerical simulations. Partially automated
optical inspection and the digital image correlation technique were used in the experimental investigation. In the
finite element analyses, an actual geometry of a cracked structure has been modeled. The mechanical material
behavior has been assumed as linear elastic in a first approach for calculating stress intensity factors. The nonlinear
nature of the cyclic deformation has been taken into account by applying a cyclic plasticity model, and
plasticity-induced crack closure is captured by a contact formulation.
