In this paper, we present a study of the simulation of Directed Energy Deposition (DED) Additive Manufacturing (AM) using a multiphysics approach. We use a combination of Heat Transfer in Fluids, Solid Mechanics and Laminar Flow physics to accurately simulate the DED process. The ... 詳細を見る
Laser drilling of titanium and its alloys is widely used in aerospace industry, as it offers selective removal of material at high accuracy and speed. However, laser drilling often inherits defects such as large heat affected zone, micro cracks and recast layer. These defects depend upon ... 詳細を見る
Electron beam has a wide range of applications in the material processing and joining techniques. Apart from that, it has also been utilized to simulate steady as well as transient fusion reactor relevant heat loads. Transient heat load events spontaneously occur in the fusion reactor. ... 詳細を見る
A solidification process of casting explosives in shell is studied in this paper. An enthalpy method approach is used to model the solidification process. Both the thermal and mechanical effects are taken into account. An ALE (Arbitrary Lagrangian-Eulerian) method is used to represent ... 詳細を見る
Laser percussion drilling is widely used in the aerospace industry to produce cooling holes in jet engine components. This process is a thermal, contact-free process which involves firing a sequence of focused optical pulses onto a target material [1-4]. During each optical pulse, the ... 詳細を見る
Simulation of arc-wire additive manufacturing is under development in many academic and industrial sectors and at different scales. The study at the melt pool scale is often interesting to study deposition shapes and defects but not very relevant to calculate the stresses and strains at ... 詳細を見る
Present work is done in the framework of the SisAl Pilot EU project, which aims at optimising the silicon production in Europe by recycling materials and using a carbon-emission friendly technology. The silicon production experiments are conducted on laboratory and pilot scales in ... 詳細を見る
The Bridgman process is used in the production of single crystal superalloys for use in high temperature applications. The mechanical properties of these superalloys are strongly influenced by the microstructure that is formed during the solidification. The formation of the ... 詳細を見る
The process-induced deformation in the DED fabricated part is a critical issue to the scaling of the technology. Currently, an inefficient and expensive experiment trial-and-error approach is utilized to tackle this issue, however it is not feasible for large parts. Researchers have ... 詳細を見る
Hot material extrusion (MEX) additive manufacturing with filament feedstock (also known as fused filament fabrication (FFF) or fused deposition modeling (FDM™)) is one of the most popular and fast-growing 3D-printing techniques for consumer and educational purposes. A continuous ... 詳細を見る
