ESIS's picture

Discussion of fracture paper #25 - The role of the fracture process region

The subject of this blog is a fracture mechanical study of soft polymers. It is well written and technically detailed which makes the reading a good investment. The paper: Experimental and numerical assessment of the work of fracture in injection-moulded low-density polyethylene, M. Kroon et al.

Discussion of fracture paper #24 - The sound of crack growth

Carbon fibre reinforced polymers combines desired features from different worlds. The fibres are stiff and hard, while the polymers are the opposite, weak, soft and with irrelevant fracture toughness. Irrelevant considering the small in-plane deformation that the fibres can handle before they break.

Discussion of fracture paper #23 - Paris' exponent m<2 and behaviour of short cracks 

I came across a very interesting paper in Engineering Fracture Mechanics about a year ago. It gives some new results of stochastic aspects of fatigue. The paper is: ”On the distribution and scatter of fatigue lives obtained 

Discussion of fracture paper #22 - Open access puts scientists in control of their own results 

The last ESIS blog about how surprisingly few scientists are willing/able to share their experimental data, received an unexpectedly large interest.
