Dr Chris Triantafyllou

Teaching Associate

Mechanical and Aerospace Engineering

Personal statement

Dr Chris Triantafyllou obtained his PhD in aerospace materials from the University of Glasgow, specialising in the cold-dwell fatigue response of titanium alloys and investigating the effects of microtexture on the mechanical properties of critical aerospace components. His research employed a coupled experimental-computational approach and contributed to a growing body of research in this area by utilising advanced experimental techniques. As a Teaching Associate in the Department of Mechanical & Aerospace Engineering, Dr Triantafyllou is involved in the development and delivery of modules related to materials science, design, and manufacturing. He encourages practical, research-driven and industry-relevant learning and actively works to establish and maintain collaborations with companies across Scotland for research and student projects. Previously, Dr. Triantafyllou has led two external educational initiatives aimed at enhancing the aerospace engineering learning experience. These initiatives included modernising syllabus content for principles of jet propulsion, as well as integrating interdisciplinary design and build projects with multiple sub-systems as an applied learning tool for undergraduate students.

Influence of Infill Density and Orientation on the Tensile and Viscoelastic Response of Additively Manufactured PLA: Triantafyllou, Chris (Principal Investigator); This is a collaborative project with the University of Glasgow and investigates the mechanical behaviour of polylactic acid (PLA) specimens manufactured via fused deposition modeling (FDM), focusing on how infill density and infill orientation influence their tensile and time-dependent viscoelastic responses. Specimens were fabricated with infill densities of 25%, 50%, and 100%, and with orientations of 90°/0° and 45°/–45°, designed to alter the internal shear load distribution during tensile deformation.

A comprehensive experimental campaign was conducted, including quasi-static tensile tests, strain rate sensitivity evaluations, and stress relaxation experiments. The aim is to assess both the immediate mechanical performance and the viscoelastic behaviour of the material under in-service loading conditions. The influence of internal structure on stiffness, strength, and time-dependent deformation was quantified. The project will inform material parameters for non-homogeneous geometries in computational investigations using Abaqus.; 01-Jan-2024 - 19-Jan-2025
