Yan, Z. (author), Zhu, Jia-Ning (author), Borisov, Evgenii (author), Riemslag, A.C. (author), Scott, S.P. (author), Hermans, M.J.M. (author), Jovanova, J. (author), Popovich, V. (author)In energy absorption applications, architectured metallic materials generally suffer from unrecoverable deformation as a result of local yield damage or inelastic buckling. Nitinol (NiTi) offers recoverable deformation and energy dissipation due to its unique superelasticity, which can change the way we design and additively manufacture...journal article 2023

Hulsman, Filippus (author)The research investigates the creation of an end-effector capable of pick-and-placing thin laminates of various materials. The chosen end-effector design induces a pressure differential with a membrane, and is capable to achieve a large switching force for various delicate and geometric complex laminates. The concept utilizes an array of holes,...master thesis 2022

Kariouh, Anass (author)Concrete is the most used building material in the world. Its success can be linked back to its mouldability, durability and low cost. Unfortunately, current conventional concrete pedestrian bridge designs do not benefit from these key features and still require bulky shaped cross-sections, whereby part of the concrete does not contribute to the...student report 2022

Ranjan, R. (author), Ayas, C. (author), Langelaar, Matthijs (author), van Keulen, A. (author)A novel constraint to prevent local overheating is presented for use in topology optimization (TO). The very basis for the constraint is the Additive Manufacturing (AM) process physics. AM enables fabrication of highly complex topologically optimized designs. However, local overheating is a major concern especially in metal AM processes...journal article 2022

Kuipers, T. (author)The products in our day to day lives have different requirements in different regions of the product. One way of dealing with such spatially varying requirements is to divide the product into multiple parts and assign each part a different material. For example, the handle of a drill is often fitted with a rubbery material which gives it more...doctoral thesis 2022

Salvati, Enrico (author), Tognan, Alessandro (author), Laurenti, L. (author), Pelegatti, Marco (author), De Bona, Francesco (author)Defects in additively manufactured materials are one of the leading sources of uncertainty in mechanical fatigue. Fracture mechanics concepts are useful to evaluate their influence, nevertheless, these approaches cannot account for the real morphology of defects. Preliminary attempts to exploit a more comprehensive description of defects can...journal article 2022

Mishra, V. (author), Ayas, C. (author), Langelaar, Matthijs (author), van Keulen, A. (author)A remarkable elastic anisotropy in plates of austenitic stainless steel produced by the Wire and Arc Additive Manufacturing process is recently reported. The Young's modulus depends on the angle of orientation with respect to the material deposition direction. Here, for the first time, this anisotropy is exploited to maximize structural...journal article 2022

Hille, Helge C. (author), Kumar, Siddhant (author), De Lorenzis, Laura (author)We propose Floating Isogeometric Analysis (FLIGA), which extends IGA to extreme deformation analysis. The method is based on a novel tensor-product construction of B-Splines for the update of the basis functions in one direction of the parametric space. With basis functions “floating” deformation-dependently in this direction, mesh distortion...journal article 2022
