Mondeel, Manouk (author)<b>BACKGROUND - </b>The success of the mechanical thrombectomy treatment in acute ischemic stroke is highly dependent on mechanical clot behavior and characteristics like stiffness. This mechanical treatment is tested in clot analogs. Realistic clot analogs could potentially be made in a realistic formation environment. The effects of blood...master thesis 2022

Aramfard, Mohammad (author), Pérez-Ràfols, Francisco (author), Nicola, L. (author)A seamless 2D dual-scale computational scheme is developed to study contact problems. The model consists of an atomistic domain close to the contact, coupled with an elastic continuum domain away from the contact. The atomistic formulation provides a description of the contact interaction through interatomic potentials and permits to capture...journal article 2022
