Modeling induced flow anisotropy and phase transformations in air hardening steels.

In this work a material model for hardening development in sheet metals during forming processes involving loading path changes is formulated. In particular, such hardening development is due to the formation and interaction of dislocation microstructures in the material, resulting in an evolution in the size, center and shape of the yield surface. Such yield surface evolution is accounted for in

Hazardous Materials Incidents - Some Key Results of a Risk Analysis

Human safety and health, environmental and property protection and security concerning hazardous materials supply chain are important issues for many countries, industries and organisations around the world. This paper presents some key results of a comprehensive risk study on hazardous materials supply chain incidents. Based on a risk analysis framework adapted for mari-time transport of packaged

Capturing better data: The potential for better insight into user's requirements through iterative prototyping

This article aims at introducing to a wider circle a complementary research approach in user oriented work. Its most fundamental part is the use of technology as a tool for capturing the needs, wishes and dreams of a user. The incitement for us to start developing this method was an experience based, serious, questioning of conventional methods such as interviews, questionnaires, etc, and their c

Morphosyntactic parasites as underspecified heads: On the double supine construction

The purpose of the present study is threefold. Firstly, I wish to investigate the phenomenon of double supines in colloquial Swedish. In doing so, I hope to achieve my second purpose, which is to take a first step towards a better understanding of a particular kind of complementation of which the double supine construction forms a subset. I will refer to this complementation as parasitic complemen

Void growth in cyclic loaded porous plastic solid

In low-cycle fatigue, where plastic strains are of great importance, final ductile fracture depends upon the mechanisms of void growth and coalescence of voids. A cell model is used to simulate a periodic array of initial spherical voids and this model is subjected to different loads that include cyclic loading. Three different types of matrix material are simulated: elastic-perfectly plastic, iso
