Servitisation through structural adaptation

Journal of Service Theory and Practice, 2021
PurposeThe purpose of this study is to investigate the structural changes needed for project-based organisations (PBOs) to synthesise their project operations and services following the servitisation strategy. It addresses the question of how PBOs should change their organisational structure fitting with service provision strategy.Design/methodology ...

Virtual testing for design and certification of (fusion) bonded longitudinal joints in a fibre composite fuselage: A proposal using FEM-based progressive damage analysis

Composites Part C: Open Access, 2022
In the design of bonded aircraft structures, the type of failure is crucial. More specifically, the failure in case of overload should be limited to the surrounding fibre composite structure.

Holistic determination of physical fracture toughness values and numerical parameters for delamination analysis considering multidirectional-interfaces

Composites Part C: Open Access, 2022
Delaminations are a concern for the structural integrity of fibre composite structures. The decisive material parameter for delaminations is fracture toughness. Structures usually have a multidirectional ply stacking.

Integrated Shock Absorber With Both Tunable Inertance and Damping

Frontiers in Materials, 2020
Inerter is a two-terminal mass element, and the applied force is proportional to the relative acceleration between the terminals. According to the second class of mechanical–electrical analogy, the inerter corresponds exactly to the capacitor in the ...

Modelling of a SMA Blade Twist System Suited for Demonstration in Wind Tunnel and Whirl Tower Plants

Applied Sciences, 2023
In this work, the modeling of a demonstrator of a morphing system aimed at altering the twist of a rotorcraft blade is presented. The device was conceived for two different representative environments: the wind tunnel plant of the University of Bristol ...

Structure-Integrated Thin-Film Supercapacitor as a Sensor

Sensors, 2022
Today, aircraft composite structures are generally over-dimensioned to avoid catastrophic failure by unseen damages. This leads to a higher system weight and therefore an unwanted increase in greenhouse gas emissions.
