A modified johnson-cook model for ferritic-pearlitic steel in dynamic strain aging regime

Abstract In this study, the flow stress behavior of ferritic-pearlitic steel (C45E steel) is investigated through isothermal compression testing at different strain rates (1 s-1, 5 s-1, and 60 s-1) and temperatures ranging from 200 to 700 °C. The stress-strain curves obtained from experimental testing were post-processed to obtain true stress-true plastic strain curves. To […]

Iterative value models generation in the engineering design process

Abstract Value models are increasingly discussed today as a means to frontload conceptual design activities in engineering design, with the final goal of reducing cost and rework associated with sub-optimal decisions made from a system perspective. However, there is no shared agreement in the research community about what a value model exactly is, how many […]

Reverse Engineered Design Automation: Applying Knowledge Based Engineering Techniques to a Case of Automotive Fixtures Design Configuration

Abstract In the production of automotive body components, fixtures are an important part of the ongoing work on geometrical assurance. The fixture is uniquely defined for each component, and the design and configuration of these are time-consuming and takes a lot of effort. The objective with this paper is to explore the use of a […]

Key factors for STPs facilitating the establishment of an innovation-advising organization network to support SMEs in developing Industry 4.0 products/services

ABSTRACT This study explores the role of science and technology parks (STPs) as facilitators in the creation of an innovation-advising organization network (IAON) within the health, social welfare, and medical technology sector (health-tech). The background to this study is that more and more products using Industry 4.0 technology, i.e., robotics, artificial intelligence, and Internet of […]

How STPs can support the implementation of Industry 4.0-products in the health-tech sector

ABSTRACT This study explores what role science and technology parks (STP) can play when aiming to increase knowledge regarding the implementation of products for the health, social welfare, and medical technology sector (health-tech), including Industry 4.0 technology-based products (products), on a national level in Sweden. Such products, have problems reaching the market due to increased […]

WORK INTEGRATION SOCIAL ENTERPRISES: A TESTBED FOR CHALLENGE-BASED LEARNING?

ABSTRACT Work Integration Social Enterprises (WISE) are a particular enterprise form permeated by a so-called ‘double business idea’. Besides the commercial imperative of providing product and services, WISE offer employment and training opportunities for individuals considered less able to compete in mainstream labour markets. The paper argues that this multiple goal structure makes WISE an […]

Modeling ‘ilities’ in early Product-Service Systems design

ABSTRACT Product-Service Systems, like all complex systems, are vulnerable to unpredictable environmental changes that can seriously undermine their ability to continuously deliver value to customers. The long-term consequences of volatile markets, unanticipated technologies, and unpredictable changes in society must be captured, modeled and communicated to decision makers since the earliest stages of the design, so to identify sustainable […]

Life cycle simulation to support cross-disciplinary decision making in early PSS design

ABSTRACT The development of early-stage simulation capabilities is a critical step in the quest for ‘frontloading’ early stage PSS design activities, reducing the cost and risk for rework associated with sub-optimal decisions. This paper describes how life cycle simulations, based on a Discrete Event approach, can be applied to support cross-disciplinary decision making in PSS design, facilitating […]

Key guidelines for designing integrated solutions to support development of marginalised societies

ABSTRACT Marginalised societies face a wide range of deprivations and constraints at individual, institutional, economic, and technological levels. To satisfy unmet or underserved needs of poor people living in these societies, it is essential to address all the relevant constraints in the target context through the design of integrated solutions. Many studies have explored the […]
