Dear iMechanicians - I hope that the following work is of interest. We oresent the first electro-chemo-mechanical model capable of predicting both hydrogen embrittlement and anodic-dissolution driven stress corrosion cracking. In this way, environmentally assisted cracking predictions can be obtained for any choice of environment and without any 'a priori' decision on the governing mechanism. This allows us to simulate for the first time seminal experiments, such as those by Ghrul on Al alloys.

I presented my new theory of QM yesterday.

Just that.

Most 4D printings utilize 1D structural deformation — bending and coiling to morph a flat shape by controlling only a single curvature, limiting the realization of complex 3D curved surfaces with two curvatures. We quantitatively analyze the morphing of a 2D plate into doubly curved surfaces on a direct 4D printing of a single isotropic material employing anisotropy of shape memory effect during the extrusion-based printing.

Dear Colleagues, 

Micromachines (ISSN 2072-666X, IF 2.891) is currently running a Special Issue entitled “Novel Devices and Advanced Fabrication in Emerging Bioinspired Systems”. I’m serving as the Guest Editor for this themed issue which is open for submission now. 

Department of Mechanical Engineering at the University of Connecticut, USA, invites applications for Postdoctoral fellow in the Laboratory for Advanced Manufacturing Reliability (https://k-kim.org/). 

1-year appointment, renewable by mutual agreement. The candidate is expected to join the team as soon as a successful interview has been completed.
