Topic

Peridynamic (PD) models are ideally suited for simulating damage (fracture, fragmentation, dissolution, corrosion, erosion, etc.) because nonlocality allows various failure mechanisms to be represented, in an average sense, seamlessly across multiple scales, while maintaining the dominant length-scale in the description. This course presents PD formulations of general material failure/degradation phenomena, including dynamic brittle fracture, shear banding and ductile failure, corrosion damage, damage in concrete structures, thermomechanical failure, fracture in composite and porous materials, etc. Furthermore, strategies to couple classical continuum mechanics and PD will be discussed and applied to the coupling of FEM meshes and PD grids. A special emphasis will be placed on transitioning from a mathematical formulation to numerical solutions. Participants will gain hands-on experience with open-source Matlab codes implementing FEM-PD coupled models to simulate crack propagation problems, and fast pseudo-spectral solvers for PD models of dynamic fracture and corrosion. Differences from other nonlocal models and confusing terms used in the published literature will be clarified. Other advanced topics will be addressed. The course is aimed at researchers and graduate students in the fields of mechanical, aerospace, civil and biomedical engineering, applied mathematics, electrochemical engineering, physics, and biophysics.

Who can apply

Undergraduate and PhD student, Post-doc, Researcher and anybody interested in recent results of the mechanics of granular suspensions is warmly invited to apply for the course. Moreover, applicants will have the possibility to show briefly their results in the context of a short Workshop included in the course and extend their research network.
