Fracture Mechanics of Welded Structures
For fracture mechanics the location and geometry of the crack or defect must be specified as input data. The crack geometry could be specified as an ordered set of points […]

Properties can be provided for a material or alloy or for a specific phase in a material or alloy. If properties are provided for a specific phase, then the macroscopic […]
If there is a weld pool solver that computes the weld pool free surface, velocity and temperature in the weld pool and weld pool reinforcement, the input data should include […]
The initial conditions include initial stress, i. e., the residual stress and initial effective plastic strain for each part in the structure if it is known. If the residual stress […]
The composition of the base metal must be specified. We prefer the format ((Fe,*), (C, 0.12), (Mn, 1.3),…). Here (Fe,*) means the balance of the fraction is Fe. We have […]
For the thermal analysis, the initial temperature of each part must be specified. The interface between the moving weld pool and its complement is a Dirichlet BC on the complement. […]
Associated with each weld pass in each weld joint is a weld pool. The weld pool may have any shape and size but its geometry must be specified as input […]
9.1 Introduction and Synopsis This section describes the author’s preferred input data for a Computational Welding Mechanics analysis of a welded structure. Often some desired input data will not be […]
Hot cracking is important in certain classes of alloys. This requires models of solidification, including segregation and texture modeling. The stress analysis near the melting point could be the most […]
Since the 1950s, more than one hundred separate and distinct weldability tests aiming at assessing the solidification and liquation cracking susceptibility have been devised and completely new or modified tests […]
