Data-Driven Reduced-Order Modeling of Convective Heat Transfer in Porous Media

Carlo Fiorina

This work presents a data-driven Reduced-Order Model (ROM) for parametric convective heat transfer problems in porous media. The intrusive Proper Orthogonal Decomposition aided Reduced-Basis (POD-RB) technique is employed to reduce the porous medium formul ...

Additive Manufacturing of Bulk Metallic Glasses-Process, Challenges and Properties: A Review

Roland Logé, Jamasp Jhabvala, Navid Sohrabi

Bulk Metallic Glasses (BMG) are metallic alloys that have the ability to solidify in an amorphous state. BMGs show enhanced properties, for instance, high hardness, strength, and excellent corrosion and wear resistance. BMGs produced by conventional method ...

Influence of local fiber distribution on tensile behavior of strain hardening UHPFRC using NDT and DIC

Eugen Brühwiler, Xiujiang Shen

This paper introduces the uniformity factor mu(2) for considering the local fiber distribution within elements made with Ultra-High Performance Fiber Reinforced Cementitious Composites (UHPFRC). The influence of mu(2) on the strain-hardening response of UH ...

Influence of thermo-mechanical history on the ordering kinetics in 18 carat Au alloys

Nadine Baluc, Steven Van Petegem, Helena Van Swygenhoven, Marina Garcia Gonzalez

Precious alloys are subjected to a series of mechanical and thermal operations during manufacturing. For 18 carat gold alloys the processing operations can induce L1(0) ordered nanodomains, known to lead to the buildup of residual stresses, which are the p ...

Tuning stiffness nonlinearty: theory and applications

Simon Nessim Henein, Ilan Vardi, Mohamed Gamal Abdelrahman Ahmed Zanaty

Perfect elasticity is not achievable in real-life situation, so spring stiffness is not perfectly constant. In this paper, we study the effect of modifying non-linear stiffness terms while keeping the nominal stiffness constant. We introduce three methods ...
