TL;DR: In this paper, a micro-mechanical model is used to study the effect of ply thickness on constrained 90° plies subjected to transverse compressive loading (in situ effect).
Abstract: A micro-mechanical model is used to study the effect of ply thickness on constrained 90° plies subjected to transverse compressive loading (in situ effect). For cross-ply sublaminates with conventional, standard-thickness 90° plies, failure is dominated by fibre–matrix interface cracking and large localised plastic deformation of the matrix, forming a localised band in a plane that is not aligned with the loading direction. Ultra-thin plies show a dispersed damage mechanism, combining wedge cracking with ply fragmentation/separation. Moreover, a transverse crack suppression effect is clearly observed. To the authors’ knowledge, it is the first time an in situ effect in transverse compression has been identified. When comparing the results of the micro-mechanical model with the predictions from analytical models for the in situ effect, the same trends are obtained. These results also show that, for realistic ply thicknesses, these analytical models can be considered fairly accurate.

17 Dec 2010TL;DR: In this paper, an arrangement for verifying a real model by using a virtual model is provided, consisting of a real tool element which has a real coordinate system, a virtual tool element that has a virtual coordinate system and a first position determination element, which is applied in/on the real model in a defined manner.
Abstract: An arrangement for verifying a real model by using a virtual model is provided. The arrangement comprises a real model which has a real coordinate system, a virtual model which has a virtual coordinate system, a first position determination element, which is applied in/on the real model in a defined manner, and a real tool element, which is arranged in the real model. A position and/or orientation of the real tool element in the real model can be determined relative to the first position determination element. An operation of the real tool element can be triggered in the real model, and the operation of the real tool element can be imaged in the virtual model. The operation of the real tool element in the real model and the imaged operation in the virtual model can be logically or functionally assigned to one another.

22 Mar 1993TL;DR: An overhead luggage compartment system for a passenger aircraft is equipped with luggage compartments formed as shells that can be adjusted in their tilted position and in their elevated position for easy access as discussed by the authors. But this system does not require any separate covers or lids for the luggage compartment.
Abstract: An overhead luggage compartment system for a passenger aircraft is equipped with luggage compartments formed as shells that can be adjusted in their tilted position and in their elevated position for easy access. In the closed position the shells are fully recessed into the ceiling structure of the aircraft cabin. Such a structure does not require any separate covers or lids for the luggage compartments. Additionally, a power drive lifts, lowers, and tilts the compartment shells. In the lowered position the shells are fully accessible even for short people. In the upper, recessed position the shells are closed and locked.

TL;DR: The concept of measurement assisted assembly (MAA) was introduced in this paper to facilitate a step change in assembly process capability and efficiency for large and complex products such as airframes, where traditional assembly processes exhibit the requirement for rectification and rework, use inflexible tooling and are largely manual, resulting in cost and cycle time pressures.
Abstract: This paper presents for the first time the concept of measurement assisted assembly (MAA) and outlines the research priorities of the realisation of this concept in the industry. MAA denotes a paradigm shift in assembly for high value and complex products and encompasses the development and use of novel metrology processes for the holistic integration and capability enhancement of key assembly and ancillary processes. A complete framework for MAA is detailed showing how this can facilitate a step change in assembly process capability and efficiency for large and complex products, such as airframes, where traditional assembly processes exhibit the requirement for rectification and rework, use inflexible tooling and are largely manual, resulting in cost and cycle time pressures. The concept of MAA encompasses a range of innovativemeasurement- assisted processes which enable rapid partto- part assembly, increased use of flexible automation, traceable quality assurance and control, reduced structure weight and improved levels of precision across the dimensional scales. A full scale industrial trial of MAA technologies has been carried out on an experimental aircraft wing demonstrating the viability of the approach while studies within 140 smaller companies have highlighted the need for better adoption of existing process capability and quality control standards. The identified research priorities for MAA include the development of both frameless and tooling embedded automated metrology networks. Other research priorities relate to the development of integrated dimensional variation management, thermal compensation algorithms as well as measurement planning and inspection of algorithms linking design to measurement and process planning. © Springer-Verlag London 2013.
