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 […]
