Material forces in microfractured bodies
Tóm tắt
In the present work, we study the overall behavior of a microfractured elastic body within the configurational mechanics framework. Micro and macro scales are considered and scale changes are carried out by asymptotic developments homogenization. The homogenized equations of material momentum and scalar moment of material momentum are obtained. In these equations the microcrack length appears as an internal variable, describing the damage evolution. Both quasistatic and dynamic formulations are presented.
