Fatigue strength of hybrid VHSS-Cast steel welded plates.

Very high strength steels (VHSS) have been made available by the steel industry for many years. In a fatigue loaded VHSS structure absolute and relative stress variation will be higher compared to stresses in structures made of lower grade steels. Cast steel, also available up to yield strength of 1100 MPa, is more and more applied in fatigue...

The fatigue strength of base material and butt welds made of S690 and S1100

Modern steel manufacturing techniques make it possible to produce steel with nominal strengths up to 1100 MPa (very high strength steels, VHSS). For the design of cyclic loaded slender VHSS structures, the fatigue strength of both base material and welded components should be known. In a VHSS fatigue loaded structure absolute and relative stress...
