Topics:
This course offers an in-depth exploration of the novel Finite Fracture Mechanics (FFM) technique for modeling crack and failure initiation, with practical applications to real-world problems. It is designed for post-graduate students, expert researchers, and engineers who wish to understand, apply, or develop this approach. Various theories predict failure initiation in complex structures with stress concentrations or singularities, such as holes or V-notch tips. FFM allows to identify the structure-specific intrinsic length scale and extends the concepts of traditional fracture mechanics to more general configurations with stress concentrations or singularities beyond just a crack tip with a square root singularity. FFM has been validated through numerous experimental observations, successfully predicting failure initiation in complex geometries. In recent years, it has been extended to 3D domains, geometrical and material nonlinearities, and dynamic aspects, including subsonic crack propagation. It has proven effective in assessing fractures at the micro- or nano-scale, in bio-inspired and 3D-printed materials and composites. Additionally, it has provided a physical explanation for the regularization parameter in phase-field models for fracture and established a link with traction-separation profiles of cohesive zone models. These extensions, applications, and interactions with other fracture models make FFM a cutting-edge approach in failure modeling, which will be thoroughly discussed. Practical applications and hands-on exercises will enable participants to master FFM techniques.
The proposed CISM course brings together six researchers who have extensively studied and applied FFM techniques. It will begin by addressing the framework and origin of FFM, including related experimental and theoretical aspects as well as numerical implementation. It will then focus on applications for a wide range of materials and configurations. Recent FFM extensions, including 3D applications, material nonlinearities such as plasticity or nonlinear elasticity, geometrical nonlinearities, dynamic and fatigue loadings, and FFM as an optimization problem, will be covered. The relationship of FFM to other fracture models will also be reviewed in detail.
Venue: CISM (International Centre for Mechanical Sciences), Lectures will take place in the beautiful Palazzo del Torso in the center of Udine
Format: The course is offered in hybrid format (presential and online).
