Mitä on tapahtunut Oulun yliopiston metallitutkimuksessa ensimmäisen puolivuosisadan aikana ? Ketkä olivat mukana siihen vaikuttamassa ? Ketkä ovat valmistuneet sieltä ? Tämä lyhyt historiikki perustuu paljolti kirjoittajan omaan kokemukseen hänen ollessaan ensin opiskelija ja jatko-opiskelija sekä sittemmin noin 35 vuoden ajan metalliopin apulaisprofessorin, professorin sekä laboratorion esimiehen toimen hoitaja. Se tuo esiin faktoja, mutta myös sellaisia omintakeisia muistikuvia, joita ei missään muualla ole kirjattu ylös. Tutkimuksen kehitys vuosikymmenten mukana teollisuuden tarpeet huomioiden ja muuttuminen hyvin kansainväliseksi tulee esille samoin kuin siihen osallistuneet henkilöt sekä Suomessa että eri puolilla maailmaa.

Special topic volume with invited peer-reviewed papers only
This book provides a basis for the design and analysis of welded components that are subjected to fluctuating forces, to avoid failure by fatigue. It is also a valuable resource for those on boards or commissions who are establishing fatigue design codes. For maximum benefit, readers should already have a working knowledge of the basics of fatigue and fracture mechanics. The purpose of designing a structure taking into consideration the limit state for fatigue damage is to ensure that the performance is satisfactory during the design life and that the survival probability is acceptable. The latter is achieved by the use of appropriate partial safety factors. This document has been prepared as the result of an initiative by Commissions XIII and XV of the International Institute of Welding (IIW).
