Modeling Behaviour of Damaged Turbine Blades for Engine Health Diagnostics and Prognostics
… gas turbine engines is largely due to careful damage tolerant design a method of structural design based on the assumption that flaws (cracks) exist in any structure and will continue to grow with usage. With proper monitoring, largely in the form of periodic inspections at conservative …

Systematic assessment of the influence of voids on the material performance and failure in additively manufactured polymers.
… provides essential information for enabling damage tolerant design considerations of FFF components, reducing the chances of catastrophic failure and simplifying supply chain of critical components with shorter lead time.

Non-linear individual and interaction phenomena associated with fatigue crack growth.
… The traditional safe-life approach to fatigue design is based upon the total time to failure of a virtually defect free component. This approach is heavily reliant on the use of safety factors and empirical equations, and therefore much scatter in the fatigue life predictions is normally …

Damage characterization and modeling of notched graphite/epoxy sandwich panels in compression
Damage tolerant design, which focuses on a structure's ability to perform in a damaged state, is widely used in the aerospace industry today. Although extensive research has been carried out in this area for notched composite laminates, a relatively small fraction has dealt with compressive loading …

Experimental and Computational Micromechanics of Aluminum Cerium Alloys and Selective Laser Melted 316L Stainless Steel
… and fabrication techniques making it possible to design and create more complex engineering components for service. If we are to include these materials in damage tolerant design efforts, engineers need to understand when/where degradation will occur in the engineering component. To do so it is …

The Effects of Load Ratio on Threshold Fatigue Crack Growth of Aluminum Alloys
… than a critical size exists. Although most well designed structures initially contain no critical cracks, subcritical cracks can grow to failure under fatigue loading, called fatigue crack growth (FCG). Because it is impossible or impractical to prevent subcritical crack growth in most …

Μελέτη διάδοσης τασικών κυμάτων σε πολύστρωτες διατάξεις ινωδών συνθέτων υλικών. Αποτίμηση δομικής ακεραιότητας κατασκευαστικών στοιχείων
Κίνητρο της παρούσας διατριβής αποτέλεσε η αποτίμηση της δομικής ακεραιότητας κελυφοειδών κατασκευών από σύνθετα υλικά που παρουσιάζουν ανοχή στη βλάβη, με τη χρήση ακουστικών τεχνικών μη καταστροφικού ελέγχου. Στόχος ήταν η πειραματική και θεωρητική μελέτη επίδρασης της αστοχίας, που αναπτύσσεται …
