Analysing the effects of 3D printing defects and surface roughness on the properties of acoustic materials
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)The principal aim of the research reported in this thesis was to investigate the influence of additive manufacturing on the acoustic performance of 3D printed periodic materials. First, a benchmark material design was ... -
Analysis of the rough contact in axisymmetric upsetting
(Trinity College Dublin. School of Engineering. Mechanical & Manufacturing Engineering, 2007)Characterization of surface roughness is important in the frictional behavior of two contact surfaces. In general, it has been found that friction increases with average roughness. The prediction of friction and stress/ ... -
The Impact of Additive Manufacturing on the Acoustic Performance of Novel Porous Materials
(2022)Commonly used conventional acoustic porous materials suffer from a limited operational frequency range and great dependency of the sample thickness on their performance. For this reason, acoustic metamaterials have caught ...
