Cs. Desai et R. Whitenack, Review of models and the disturbed state concept for thermomechanical analysis in electronic packaging, J ELEC PACK, 123(1), 2001, pp. 19-33
A number of models for thermomechanical stress analysis and fatigue failure
of materials are reviewed and their capabilities and limitations are ident
ified. The unified disturbed state concept (DSC)for constitutive,modeling o
f materials and interfaces is presented and compared with other approaches.
An approximate procedure based on the DSC is proposed for accelerated desi
gn-analysis and cyclic fatigue failure. Solutions of example problems using
the DSC and associated computer (FE) procedures are included to illustrate
its integrated and improved capabilities for analysis of stresses, strains
, microcracking, fracture and fatigue failure, and reliability.
