Journal ArticleDOI
Thermomechanical analyses of ultrasonic welding process using thermal and acoustic softening effects
Amir Siddiq,Elaheh Ghassemieh +1 more
TL;DR: In this article, a very first attempt has been made to simulate the ultrasonic welding of metals by taking into account both of these effects (surface and volume) and a phenomenological material model has been proposed which incorporates these two effects (i.e. surface and volume).
Journal ArticleDOI
Numerical investigation of the effects of drill geometry on drilling induced delamination of carbon fiber reinforced composites
Ozden Isbilir,Elaheh Ghassemieh +1 more
TL;DR: In this paper, a 3D FE model for drilling composite laminates is presented, which includes a progressive intra-laminar failure model based on the Hashin's theory and an interlaminar delamination model which includes the onset and growth of delamination.
Journal ArticleDOI
Comparative study of tool life and hole quality in drilling of cfrp/titanium stack using coated carbide drill
Ozden Isbilir,Elaheh Ghassemieh +1 more
TL;DR: In this paper, the effects of process parameters have been investigated, including thrust force, torque, burr formation, delamination, surface roughness and tool wear on carbon fiber reinforced plastics (CFRP) and titanium.
Journal ArticleDOI
Finite element analysis of drilling of titanium alloy
Ozden Isbilir,Elaheh Ghassemieh +1 more
TL;DR: In this article, a 3D model is developed using commercial finite element software ABAQUS/Explicit to simulate the drilling process by taking into account of the damage initiation and evolution of the work piece material, a contact model at the interface between drill bit and work piece and the process parameters.
Journal ArticleDOI
Finite Element Analysis of Drilling of Carbon Fibre Reinforced Composites
Ozden Isbilir,Elaheh Ghassemieh +1 more
TL;DR: In this paper, a 3D finite element (FE) model is developed of the process of drilling in the carbon fiber reinforced composite (CFC), which is used to investigate the effects of cutting speed and feed rate on thrust force, torque and delamination in the drilling of CFC.
