The first wall (FW) of ITER blanket includes beryllium (Be) armor tiles joined to CuCrZr heat sink with stainless steel (SS) cooling tube and backing plate in order to improve plasma performance and reduce thermal stress. Since these joints must withstand thermal and mechanical loads caused by the plasma and electromagnetic force, it is important to evaluate the strength and thermal fatigue lif...

This paper provides data on stress concentration factors (SCFs) from experimental measurements cruciform tubular joints of a chord and brace intersection under axial loading. High-fidelity finite element models were generated validated against these measurements. Further, the statistical variation uncertainty in both experiments analysis (FEA) are studied, including effect modelling weld profil...

Conclusions The present study has investigated the problem of the elastic response of a generic space vehicle with degraded joints. The steppedbeam formulation based on elementary beam theory is employed for extracting modal parameters of a normalized generic space vehicle. Next, the modal superposition principle is used with a low damping value for obtaining the elastic response of the vehicle...
