An approach to using Weibull stress analysis in design
conference paper
Current codes and norms allow for structures to be operated in the transition between ductile and brittle behavior. Further, they often treat the Ductile to Brittle Transition Temperature as a constant even though it is well known to depend on a variety of factors, such as loading rate, constraint, and prior cold deformation. This paper roposes a method whereby the Beremin approach to cleavage modelling is used to shift the DBTT in the design process, thus allowing for the DBTT to be adjusted automatically based on the actual design condition of the structure.
