Impact Performance of Advanced High Strength Steel Thin-Walled Columns
The crashworthiness performance of spot-welded columns fabricated with advanced high strength steels is evaluated using finite element (FE) analysis. A failure criterion for the spot-welds is implemented into the FE model to predict accurately the progressive axial collapse of the columns. The behavior of two Dual Phase (DP) steels and a High Strength Low Alloy (HSLA) steel are compared by examining the mean crushing force, peak load and crushed column length for single-hat and double-hat configurations, both experimentally and numerically. Numerical results of the developed FE model correlate favorably available experimental data for different impact conditions.
The whole is more than the sum of its parts
The latest program of the international steel consortium is more ambitious than its predecessors. With the introduction of the ULSAB ”Advanced Vehicle Concepts” Program (ULSABAVC), the steel consortium presents overall vehicle concepts instead of the previous programs, where individual optimised systems were presented.
Beyond East–West: Marginality and National Dignity in Finnish Identity Construction
Since the end of the Cold War it has become common for Finnish academics and politicians alike to frame debates about Finnish national identity in terms of locating Finland somewhere along a continuum between East and West. Indeed, for politicians, properly locating oneself (and therefore Finland) along this continuum has often been seen as central to the winning and losing of elections. For example, the 1994 referendum on EU membership was largely interpreted precisely as an opportunity to relocate Finland further to the West. Indeed, the tendency to depict Finnish history in terms of a series of “Westernizing” moves has been notable, but has also betrayed some of the politicized elements of this view. However, this framing of Finnish national identity discourse is not only sometimes politicized but arguably is also too simplified and results in blindness towards other identity narratives that have also been important through Finnish history, and that are also evident (but rarely recognized) today as well. In this article we aim to highlight one of these that we argue has played a key role in locating Finland in the world and in formulating notions of what Finland is about, what historical role and mission it has been understood as destined to play, and what futures for the nation have been conceptualized as possible and as providing a source of subjectivity and national dignity.
