More and more organizations recognize the need for digitalization. An essential concept in this context is the Digital Twin (DT). At its core, a DT is a virtual representation of physical reality and the associated data exchange. Despite its relevance, practice shows that the application of true DTs is relatively low. Often benefits are intangible...

Digital Twin (DT) is an important concept in research and practice. Its relevance spans across all product life cycle phases, including design, prototyping, manufacturing, service, and disposal. Despite its attention, practical examples of DTs in product design and manufacturing are scarce. One of the reasons for this is little understanding of the...

The term Digital Twin (DT) is highly prevalent in manufacturing organizations and academic research. A DT is a virtual representation of a physical entity that mirrors its states and properties. According to common definitions , a true DT has the ability to change its physical entity. In practice, however, implementations are often only sub-categor...

The Digital Twin (DT), including its sub-categories Digital Model (DM) and Digital Shadow (DS), is a promising concept in the context of Smart Manufacturing and Industry 4.0. With ongoing maturation of its fundamental technologies like Simulation, Internet of Things (IoT), Cyber-Physical Systems (CPS), Artificial Intelligence (AI) and Big Data, DT...

Digital Twins (DT) encompass virtual models interconnected with a physical system through data links. Although DTs hold significant potential for positive organisational impact, their successful adoption in industrial practice remains limited. Whereas existing research predominantly focuses on technical challenges, more recent studies underscore th...

The extensive body of research dedicated to optimizing energy consumption and efficiency in the manufacturing sector demonstrates a significant and well-established legacy. Despite a peak of publications in this field over recent years, the subject of reusing residual energy is only infrequently discussed. Where authors target this topic, research...

Ultrasonic welding is well known as a promising assembly technology for thermoplastic composite structures due to its ability to achieve high-strength joints and high efficiency. To ensure uniform transmission of ultrasonic vibration to the weld interface with the objective of producing high-quality welds, consistent contact between the sonotrode a...
