Smeared cracking, plasticity, creep, and thermal loading - A unified approach. (English) Zbl 0607.73109

A recently proposed smeared crack model which properly handles nonorthogonal cracks is further elaborated. It is proved that the model obeys the principle of material frame-indifference and some comments on possible stress-strain laws within a smeared crack are made. Algorithms are presented or indicated for the combination of plasticity and possibly multiple crack formation, for the combination of viscoelasticity and cracking, and for the combination of cracking and temperature-dependent material properties and phenomena like thermal dilatation and shrinkage.
