Crack Models with Embedded Discontinuities

摘要

1 Fracture Problem Approaches Based on Continuum Constitutive Relations This chapter presents a methodological approach for modeling concrete crack problems based on continuum constitutive relations and strong discontinuity kinematics. Fundamental aspects of this approach are presented in the initial Sections 1-2. The topics and ideas discussed in those points follow closely the work of Oliver (2002). A Finite Element technique with embedded strong discontinuities, particularly adapted for this methodology, is shown in Section 3. In the final Sections 4-6, some algorithmic aspects and several applications of the approach are addressed.
