Applied Fracture Mechanics

FSI-9ALMAcad. year: 2020/2021

Applied Fracture Mechanics – Fundamentals and Applications
This course for PhD students provides treatment of fracture mechanics that should appear to a relatively wide audience. Theoretical background and practical applications for metals, polymers and ceramic are covered in detail. Theoretical part: fundamental concepts of linear elastic and elastic-plastic fracture mechanics; micromechanisms of fracture in metals, polymers, ceramics and composites. Application - experimental part: practical procedure to fracture toughness testing in metals; standard test methods, such as KIc, KId, JIc and Ji-da curves determination, as well as recent research results; fracture testing of non metallic materials (ceramics, polymers); available methods for applying fracture mechanics to structures; fracture mechanics approach to fatigue crack propagation.

Learning outcomes of the course unit

PhD student will obtain knowledge about fracture toughness measurements methods and procedures for different kinds of material (metals, ceramics, polymers and their composites). And, in addition, obtained data interpretation and fracture mechanics applications in engineering and development is to be enlighted.

Prerequisites
