A micromechanics-based deep learning model for short fiber composites
If you are curious about application of machine learning techniques in mechanics problems, our latest paper is probably interesting for you. In this paper, we are proposing a micromechanics-based artificial neural networks model for short fiber composites.

Proposals are now invited to organize symposia at the 19th USNC/TAM. For more information, go to: http://www.usnctam2022.org/.
Journal Club For April 2021: Variational phase-field modeling of brittle and cohesive fracture
The Journal Club for April 2021 presents a concise review of the so-called variational phase-field fracture theory for brittle and cohesive fracture. Topics include the pioneering work of Griffith on brittle fracture in 1920, Barenblatt's cohesive zone model in 1959, to Marigo/Francfort's variational formulation of Griffith's brittle fracture 78 years later and the Bourdin's phase-field regularisation of MF's model. Also discussed is recent models for cohesive fracture, the role of the length scale parameter, solver for the coupled PDEs and some applications.
About glancing hypervelocity impacts
When studying impacts, including hypervelocity, one tends to put aside the fact that both the target and the impacter are moving....assuming that the target stands still. We call that situation a "glancing impact" and study it in the attached.
Azimutal dependence of hypervelocity impacts on tubes
A very simple question albeit seldom if not addressed in the literature. Not all impacts were born equal. Follow up on R-gate or soon in J. Dynamic Behavior of Materials.
