Creep of Prestressing Steels in Fire

Our new paper, Creep of Prestressing Steels in fire, is now in press in the journal Fire and Materials (you can access it here; an open access version is to come). It is a great piece about prestressing steels used in Post-tensioned structures. We show how high- temperature creep is effected by the chemical composition of…

Necking of steel

  One of the great things of testing materials with image correlation technologies at ambient and high temperatures is developing educational movies about engineering. Last summer Tom Parker and myself compiled thousands of images from my digital image correlation experiments into these videos. I've posted one example above which is to help teach the principles behind necking of steel…
