Fatigue

Dear iMechanicians,

I would like to invite you to the prepared 8th volume of the Workshop on Computational Fatigue Analysis series. The 2018 volume is dedicated to the FKM-Guideline on Strength Assessment, which covers both static and fatigue analysis of common industrial components. The key lecturer this time is Dr Roland Rennert from IMA Dresden, one of the co-authors of its last 6th revised version released in 2012.

Dear Colleagues,

This is a gentle reminder that the 2018 Midwest Mechanics Workshop will take place at IIT, Chicago on Thursday, August 9.  The deadline for registration is July 26, so we will have time to figure out the logistics. Note that registration is free for this one-day workshop. Please see:

Bones not only support and protect the various organs of our body but provide structure and enable mobility making them the most important structural materials in the human body. While aging, diet and health are known to significantly affect the structural integrity and fracture resistance of bone, fatigue, a significantly more important loading condition, is rarely studied.

Composites are used more and more as structural components in aerospace industry, automotive sector, wind energy applications,… As a consequence, the loads on those composite components are much higher than for secondary components, and can lead to fatigue damage in the composite part. Moreover, the fatigue behaviour of fibre-reinforced composites is much more complex than that of metals, because of the many different fibre/polymer combinations, the heterogeneous nature of the composite, the anisotropic behaviour of the composite and the multitude of damage mechanisms.

Dear Colleagues,

Here is our recent paper “Fatigue Fracture of Self-Recovery Hydrogels”. To the hydrogel community, this paper distinguishes the fatigue fracture and the self-recovery of a hydrogel. To the mechanics community, we show that, for the first time in hydrogels, the fatigue threshold depends only on the covalent network, but not on the noncovalent interactions that provide dissipation.
