Thermal and Mechanical Analysis of Welded Structures.
Abstract
The prediction of the residual state of stress and deformation in a welded structure is one of the most interesting and complex problems in structural mechanics. Stress analysis is considered to be a straightforward application for general-purpose, nonlinear finite element structural programs. A few special features of such analyses, are discussed: (1) the legitimacy of time-dependent plasticity theories for treating the residual stress problem; (2) criteria for choosing plane stress, plane strain, generalized plane strain, or fully three-dimensional models; (3) methods for coping with possible floating solid regions during cooling; and (4) the use of linear constraints to treat weld metal deposition and intermittent contact.
