The investigation of fatigue strength needs an accurate solution and reliable values of the stress intensity factor (SIF). In this study, SIF of load-carrying cruciform welded joints has been evaluated using finite element method (FEM), and compared with the available solutions from literature. Load-carrying cruciform welded joints with isosceles triangles and non-isosceles triangle fillet weld...

Since the Gulf war, defense missile systems against tactical ballistic missiles have been highlighted and the author also have published some studies. Recently some studies also have appeared, however, it seems that the threat of anti-surface-missiles (ASMs) to current ground sites and its countermeasures have not been sufficiently studied to date.
