This limits the use of high strength carbon steel, such as steel grade X80 or higher. The yielding check implicitly covers other failure modes as well. To extend the material grade beyond the current limit, explicit checks for other failure modes may be necessary; see Chapter 4. DNV-OS-...
If the allowable normal stress for the bar is {eq}\sigma_{allow} {/eq} = 120 MPa, determine the maximum axial force {eq}P {/eq} that can be applied to the bar. Maximum allowable stress Maximum allowable stress developed at ...
The original structures were made of SM490 steel and designed using the allowable working stress based method. The manufacturer of the crane wanted to make the structures using HSB500 steel and to redesign them applying an advanced design technology. For this purpose, the ultimate strength ...
