Flip-chip assembly of photonic components can be achieved at room temperature by using 10 μm pitch interconnects made of metallised oxide microtubes inserted into ductile reception pads. In order to reduce the electrical resistance of interconnects and the assembly force required, interconnect design in regard to geometry and materials used are opt...
This study proposes a model for the influence of work hardening and microstructure on the thermal relaxation of residual stresses. To construct such a model, an experimental campaign is first conducted on shot peened samples of Inconel 718 to generate different levels of residual stress and work hardening. The effect of the grain size and the size ...
Local authorities have a strategic role in mitigating the environmental impacts of the transport sector. However, they struggle to integrate environmental issues into their decision-making processes, especially planning. In the European context of the Sustainable Urban Mobility Plan approach and Strategic Environmental Assessments (SEAs), this pape...
Nanostructured materials containing nickel improve the effectiveness of several applications. This study examines the preparation and characterization of nanostructured Ni80Co17Mo3 alloy powders using high-energy mechanical alloying and subsequent annealing. A 72 h milling process used pure elemental powders to synthesise nanocrystalline FCC-NiCo(M...

As a first step toward a multi-fidelity optimization tool for hydrofoils, the present work assesses the ability of the in-house code PUFFIn to be used as a “low-fidelity” solver within the multi-fidelity framework. The code, based on the Boundary Element Method (BEM) and the potential flow theory, is used to study the performance of a typical winds...
This paper describes an innovative method developed by the authors to support basic decisions concerning the structural restoration of a large historical panel painting which had been damaged by inappropriate attachment to a wall and ongoing exposure to severe changes in environmental humidity. The Lapidazione di Santo Stefano is a large panel (2.7...
Climate events are increasingly affecting supply chains, leading to frequent and costly impacts. Managers lack a systematic approach to evaluate risks to individual facilities and employees. We propose a decision support methodology to help quantify the exposure of both to ten most common climate hazards. Using both historical and scenario-based cl...
Recent advances have prominently highlighted physics informed neural networks (PINNs) as an efficient methodology for solving partial differential equations (PDEs). The present paper proposes a proof of concept exploring the use of PINNs as an alternative to finite element (FE) solvers in both classical and gradient-enhanced solid mechanics. To thi...
Pressure Ulcer (PU) prevention remains a main public health issue. The physiopathology of this injury is not fully understood, and satisfactory ther-apy is currently not available. A better assessment of the internal behavior could allow to enhance the modeling of the transmission of loads into the different structures composing the heel. Computati...
