Cutting forces prediction and thermal distribution considering various cutting parameters and wear progression in drilling

Ioannis Mirisidis

The purpose of this paper is to develop a finite element method (FEM) supported simulation of drilling process applied to superficially hardened steels and assess the heat…

Finite element analysis and improved design of large-scale belt-conveyor drums

Athanassios Mihailidis, George Savaidis, Emmanouil Bouras, Emmanouil Athanasopoulos, Nikolaos Ganavaras, Ioannis Topalidis, Dimitrios Karageorgos, Ilias Rampidis

Large-scale belt-conveyor systems are extensively used in open mines to continuously transport bulk material. Conveyor pulleys are critical components and failures have…

Estimation of local properties in welded joints using samples with simulated microstructure

Pawel Kucharczyk, Sebastian Münstermann

The purpose of this paper is to determine local properties in a coarse grain zone of 10 mm thick butt welded joints made of structural S355 and high strength S960 steels…

Failure analysis of an aluminum extrusion aircraft wing component

Konstantinos Stamoulis, Dimitrios Panagiotopoulos, George Pantazopoulos, Spyros Papaefthymiou

The purpose of this paper is to deal with the failure analysis of a fractured spar stiffener, extruded from 7075-T6 aluminum alloy, which was found in the central wing, trailing…

Influence of lignin modification on the mechanical properties of lignin/PEO blends

Stavros C. Anagnou, Eleni G. Milioni, Costas S. Mpalias, Ioannis A. Kartsonakis, Elias P. Koumoulos, Costas A. Charitidis
