A new methodology for prediction of fracture initiation in hot compression of Ti40 titanium alloy

It is well known that once plastic deformation reaches a certain limit, metal materials may undergo ductile fracture, which will affect the workability of engineering materials. The accurate prediction of a material ductile fracture is thus of practical importance in the optimization of processes and improvement of products. The knowledge of the strain paths at a critical fracture site of a deforming material is helpful to study the detailed...
